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.
To find the GCF of 3 numbers you first need to write them as their prime factors: 32 = 2x2x2x2x2 40 = 2x2x2x5 64 = 2x2x2x2x2x2 The next step is to identify any common factors. In this case, all three numbers have three 2s as prime factors. Multiply these together to find the GCF: 2x2x2 = 8 Thus the GCF of 32, 40 and 64 is 8.
40% of 32= 40% * 32= 0.4 * 32= 12.8
