1, 2, 4, 8
The common factors are: 1, 2, 4, 8
1,2
The factors of 32 are 1, 2, 4, 8, 16 and 32. The factors of 40 are 1, 2, 4, 5, 8, 10, 20 and 40. The common factors are 1, 2, 4 and 8. The Higest Common Factor (HCF) is 8.
The GCF is 8.
A simple way to find the common factors of any set of numbers is to find all the factors of each one. For example: Let A be all the factors of 24. Let B be all the factors of 32. Let C be all the factors of 40. A = {1,2,3,4,6,8,12,24} B = {1,2,4,8,16,32} C = {1,2,4,5,8,10,20,40} So now we find the intersection (that is all the numbers that are common in all of the sets) of all three sets of factors. A∩B∩C = {1,2,4,8} Therefore, the common factors of 24, 32 and 40 are 1, 2, 4 and 8.
Factors of 32 2 * 2 * 2 * 2 * 2 = 32 Factors of 40 2 * 4 * 5 = 40 Only the number 5 is not a common factor because you can take two 2s from the 32 and make them a four.
The GCF of 32 and 40 is 8.The factors of 32 are 1, 2, 4, 8, 16, and 32.The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40.The common factors are 1, 2, 4, and 8, so the greatest common factor is 8.You can also determine the greatest common factor from the prime factors.The prime factors of 32 are 2, 2, 2, 2, and 2.The prime factors of 40 are 2, 2, 2, and 5.The prime factors they have in common are 2, 2, and 2, so the greatest common factor is 2 x 2 x 2 = 8.It is: 8The GCF is 8.
The common factors are: 1, 2, 4, 8
The factors of 40 are 1,2,4,5,8,10,20 and 40. For them to be common, they need to be compared to another set of factors.
The GCF of 16, 32, and 40 is 8. The factors of 16 are 1, 2, 4, 8, and 16 The factors of 32 are 1, 2, 4, 8, 16, and 32 The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40 The GCF of 16, 32 and 40 is 8.
