The GCF is 2.
The GCF of 18, 20, and 32 is 2. Factors of 18... 1,2,3,6,9 & 18 Factors of 20... 1,2,4,5,10 & 20 Factors of 32... 1,2,4,8,16 & 32... Therefore the GCF would be 2 !
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.
The lowest common multiple of 16 and 20 is 80.
The factors of 24 are: 1, 2, 3, 4, 6, 8, 12, and 24.The prime factors of 24 are: 2 and 3.The factors of 28 are: 1, 2, 4, 7, 14, and 28.The prime factors of 28 are: 2 and 7.
The common factors of 24, 32, and 36 are: 1, 2, and 4
Common factors of 24, 28, and 32 are: 1, 2, and 4.
Common factors of 20 and 32 include 1, 2, and 4
The numbers 24 and 32 have 4 common factors, and they are 1, 2, 4 and 8, with 8 being the largest.
The GCF of 12, 20, 24, and 32 is 4
