What are factors of 40?

The number 40 is an also composite number. Because it is even, the will have actually 2 as its factor. To recognize why that is composite, let"s remind the an interpretation of a composite number. A number is claimed to it is in composite if the has an ext than 2 factors. Consider the number 13. It has only 2 factors, 1 and also 13 which way that the is prime. Now, let"s take the instance of 48. The components of 48 are 1, 2, 3, 4, 6, 8, 12, 16, 24, and also 48. There are an ext than two components of 14. Therefore it is composite. Because of this factors that 40 are all the integers the 40 deserve to be divided into which room 1, 2, 4, 8, 10, 20, 40.


Step 1: Let"s begin calculating the determinants of 40, beginning with the smallest whole number, i.e., 1.Step 2: divide 40 with this number. Is the remainder 0?Yes! So, us will obtain 40 ÷ 1 = 40, and also the remainder is 0.Step 3: The next entirety number is 2. Currently divide 40 with this number. 40 ÷ 2 = 20Proceeding in a similar manner, we obtain 40 = 1× 40 = 2 × 20 = 4 ×10 = 5 × 8.Hence, the determinants of 40 room 1, 2, 4, 5, 8, 10, 20, and also 40.

Factors the 40 by prime Factorization

Prime factorization way expressing a composite number together the product of its prime factors. To acquire the element factorization that 40, we divide it by its the smallest prime factor, which is 2, 40 ÷ 2 = 20. Now, 20 is divided by its smallest prime factor and also the quotient is obtained. This process goes on till we gain the quotient as 1.

The element factorization of 40 is presented below:

*

Now that we have actually done the element factorization that 40, we have the right to multiply it and also get the various other factors. Have the right to you shot to find out if every the factors are covered or not? and as you might have already guessed, because that prime numbers, there are no other factors.

Important Notes:

As 40 ends through the digit 0, it will have 5 and also 10 together its factors. This holds for any number that ends v the digit 0.40 is a non-perfect square number. Thus, the will have an even number of factors. This property holds because that every non-perfect square number.

Factors the 40 in Pairs


The pairs of number which offer 40 once multiplied are recognized as element pairs the 40. The adhering to are the components of 40 in pairs.

determinants Pair element 1 × 40 = 40 (1,40) 2 × 20= 40 (2,20) 4 × 10 = 40 (4,10) 5 × 8 = 40 (5,8) 8 × 5 = 40 (8,5) 10 × 4 = 40 (10,4) 20 × 2 = 40 (20,2) 40 × 1 = 40 (40,1)Observe in the table above, after 5 × 8, the components start repeating. So, that is sufficient to find components till (5,8)If us consider an adverse integers, then both the numbers in the pair components will be negative. We understand that - ve × - ve = +veSo, we have the right to have factor pairs of 40 together (-1,-40) ; (-2,-20); (-4,-10); (-5,-8)

Challenging Questions:

Are 0.4 and 100 components of 40? Why carry out you think so?Are -5 and 8 factors of 40? Why execute you think so?

The length and also breadth of the first rectangular paper are 8 inches and 5 inches, and also the length and breadth of the second rectangular document are 10 inches and also 4 inches. They ar the two rectangles one end another. Since the 2 shapes do not overlap, Peter claimed that castle don"t have actually the very same area. However, Andrew does not agree with him. Have the right to you uncover out that is correct?

Solution: Area the a rectangle = length × breadthFor the very first rectangle, Area = 8 × 5 = 40For the 2nd rectangle, Area = 10 × 4 = 40Hence, the 2 rectangles have equal areas and Andrew is correct.


Example 2: Jill has (-4) as among the determinants of 40. How will she get the various other factor?

Solution: 40 = factor 1 × variable 2, for this reason we deserve to say the 40 = (-4) × element 2. Now, calculating for element 2, factor 2 = 40 ÷ (-4) = (-10).

Hence, the other element is -10.
