Given numbers are 677, 493, 855, 980

The list of prime factors of all numbers are

Prime factors of 677 are 677

Prime factors of 493 are 17 x 29

Prime factors of 855 are 3 x 3 x 5 x 19

Prime factors of 980 are 2 x 2 x 5 x 7 x 7

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

Given numbers are 677, 493, 855, 980

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

Apply this formula for all numbers.

Step1:

LCM(677, 493) = 333761

GCD(677, 493) = ( 677 x 493 ) / 333761

= 677 / 493

= 677

Step2:

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

= 1 / 855

= 1

Step3:

LCM(1, 980) = 980

GCD(1, 980) = ( 1 x 980 ) / 980

= 1 / 980

= 1

So, Greatest Common Divisor of 677, 493, 855, 980 is 1
