Given numbers are 915, 642, 986, 677

The list of prime factors of all numbers are

Prime factors of 915 are 3 x 5 x 61

Prime factors of 642 are 2 x 3 x 107

Prime factors of 986 are 2 x 17 x 29

Prime factors of 677 are 677

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

Given numbers are 915, 642, 986, 677

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

Apply this formula for all numbers.

Step1:

LCM(915, 642) = 195810

GCD(915, 642) = ( 915 x 642 ) / 195810

= 915 / 642

= 915

Step2:

LCM(3, 986) = 2958

GCD(3, 986) = ( 3 x 986 ) / 2958

= 3 / 986

= 3

Step3:

LCM(1, 677) = 677

GCD(1, 677) = ( 1 x 677 ) / 677

= 1 / 677

= 1

So, Greatest Common Divisor of 915, 642, 986, 677 is 1
