Any of its factors which are: 1, 7, 13 and 91
To find the greatest common factor of three numbers, you need to first express them as the product of their prime factors. In this case, 52 65 and 91 can be expressed as follows: 52 = 2x2x13 65 = 5x13 91 = 7x13 The next step is to identify any common factors. In this case, the only factor which appears in all 3 numbers' prime factors is 13. Thus the greatest common factor of 52, 65 and 91 is 13.
factors: 1, 5, 7, 13, 35, 65, 91, 455prime factors: 5, 7, 13
The common factors of 91 and 14 are: 1 and 7
455 has these eight factors: 1 5 7 13 35 65 91 455.
65 + 91 = 156
91
It's 13 because 65: 1, 5, 13, 65 91: 1, 7, 13, 91
