Given numbers are 649, 252, 861, 915

The list of prime factors of all numbers are

Prime factors of 649 are 11 x 59

Prime factors of 252 are 2 x 2 x 3 x 3 x 7

Prime factors of 861 are 3 x 7 x 41

Prime factors of 915 are 3 x 5 x 61

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

Given numbers are 649, 252, 861, 915

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

Apply this formula for all numbers.

Step1:

LCM(649, 252) = 163548

GCD(649, 252) = ( 649 x 252 ) / 163548

= 649 / 252

= 649

Step2:

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

= 1 / 861

= 1

Step3:

LCM(1, 915) = 915

GCD(1, 915) = ( 1 x 915 ) / 915

= 1 / 915

= 1

So, Greatest Common Divisor of 649, 252, 861, 915 is 1
