Given numbers are 861, 760, 977, 676

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 760 are 2 x 2 x 2 x 5 x 19

Prime factors of 977 are 977

Prime factors of 676 are 2 x 2 x 13 x 13

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

Given numbers are 861, 760, 977, 676

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

Apply this formula for all numbers.

Step1:

LCM(861, 760) = 654360

GCD(861, 760) = ( 861 x 760 ) / 654360

= 861 / 760

= 861

Step2:

LCM(1, 977) = 977

GCD(1, 977) = ( 1 x 977 ) / 977

= 1 / 977

= 1

Step3:

LCM(1, 676) = 676

GCD(1, 676) = ( 1 x 676 ) / 676

= 1 / 676

= 1

So, Greatest Common Divisor of 861, 760, 977, 676 is 1
