8 is the answer because 24=1,2,3,4,6,8,12 and 24 32=1,2,4,8,16 and 32 40=1,2,4,5,8,10,20 and 40 the common number in everything is 8
To find the Greatest Common Factor (GCF) of the numbers 32, 24, and 40, we first list the factors of each number:
32: 1, 2, 4, 8, 16, 32
24: 1, 2, 3, 4, 6, 8, 12, 24
40: 1, 2, 4, 5, 8, 10, 20, 40
Next, we identify the common factors that all three numbers share: 1, 2, 4, and 8.
The largest of these common factors is 8, so the GCF of 32, 24, and 40 is 8.
The greatest common factor (GCF) of 32, 24, and 40 is 8, which is determined by finding the prime factorization of each number and identifying the smallest power of the common prime factor.
