Given numbers are 915, 220, 432, 647

The list of prime factors of all numbers are

Prime factors of 915 are 3 x 5 x 61

Prime factors of 220 are 2 x 2 x 5 x 11

Prime factors of 432 are 2 x 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 647 are 647

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 915, 220, 432, 647

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(915, 220) = 40260

GCD(915, 220) = ( 915 x 220 ) / 40260

= 915 / 220

= 915

Step2:

LCM(5, 432) = 2160

GCD(5, 432) = ( 5 x 432 ) / 2160

= 5 / 432

= 5

Step3:

LCM(1, 647) = 647

GCD(1, 647) = ( 1 x 647 ) / 647

= 1 / 647

= 1

So, Greatest Common Divisor of 915, 220, 432, 647 is 1
