Given numbers are 915, 742, 646, 520

The list of prime factors of all numbers are

Prime factors of 915 are 3 x 5 x 61

Prime factors of 742 are 2 x 7 x 53

Prime factors of 646 are 2 x 17 x 19

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

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

Given numbers are 915, 742, 646, 520

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

Apply this formula for all numbers.

Step1:

LCM(915, 742) = 678930

GCD(915, 742) = ( 915 x 742 ) / 678930

= 915 / 742

= 915

Step2:

LCM(1, 646) = 646

GCD(1, 646) = ( 1 x 646 ) / 646

= 1 / 646

= 1

Step3:

LCM(1, 520) = 520

GCD(1, 520) = ( 1 x 520 ) / 520

= 1 / 520

= 1

So, Greatest Common Divisor of 915, 742, 646, 520 is 1
