Explaining how to find all factors pairs of 40 is easy. All you have to do is find which whole numbers 40 can be divided into.
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.
Common factors of 24 and 40 are: 1, 2, 4, and 8.
2 and 5
Two of the factors of 40 are odd. The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40
Explaining how to find all factors pairs of 40 is easy. All you have to do is find which whole numbers 40 can be divided into.
The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40
all the factors of 40 are 1, 2, 4, 5, 8, 10, 20, 40
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.
Divide 40 by 1, 2, 4 and 5. 1, 2, 4, 5, 8, 10, 20, 40
All of the numbers between 40 and 50 can be factors. The common factors of 40 and 50 are 1, 2, 5 and 10.
Divide by 2 until you get to 5. 1, 2, 4, 5, 8, 10, 20, 40
Divide 40 by 1, 2, 4 and 5. 1, 2, 4, 5, 8, 10, 20, 40
The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40.
The product of all of the factors of 40 is (1, 2, 4, 5, 8, 10, 20, 40) : 2,560,000
One way to determine the common factors is to find all the factors of the numbers and compare them. The factors of 15 are 1, 3, 5, and 15. The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40. The common factors are 1 and 5. The greatest common factor is 5.
Since 20 is a factor of 40, all of its factors are common.
