Given numbers are 977, 649, 420, 568

The list of prime factors of all numbers are

Prime factors of 977 are 977

Prime factors of 649 are 11 x 59

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 568 are 2 x 2 x 2 x 71

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

Given numbers are 977, 649, 420, 568

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

Apply this formula for all numbers.

Step1:

LCM(977, 649) = 634073

GCD(977, 649) = ( 977 x 649 ) / 634073

= 977 / 649

= 977

Step2:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

Step3:

LCM(1, 568) = 568

GCD(1, 568) = ( 1 x 568 ) / 568

= 1 / 568

= 1

So, Greatest Common Divisor of 977, 649, 420, 568 is 1
