Factors of 36: 1, 2, 3, 4, 6, 9, 12, 18, and 36Factors of 45: 1, 3, 5, 9, 15, and 45Common factors: 1, 3, and 9
Common factors include 1, 3 and 9.

The factors of 45 are: 1, 3, 5, 9, 15, 45 The factors of 72 are: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
Since 36 is a factor of 72, all of its factors are included in the factors of 72.

1 and 3
I think 36 has the most factors: 36 = 2*2*3*3 -> 1,2,3,4,6,9,12,18,36
Factors of 36: 1, 2, 3, 4, 6, 9, 12, 18, and 36Factors of 45: 1, 3, 5, 9, 15, and 45Common factors: 1, 3, and 9
1, 3 and 9
To find the HCF of two numbers you first have to split them into their prime factors: 45 = 3x3x5 36 = 2x2x3x3 The next step is to identify any common prime factors. In this example, both numbers have two 3s as prime factors. Multiply these together and you get: 3x3 = 9 Thus the hcf of 45 and 36 is 9.
