Given numbers are 687, 268, 980, 681

The list of prime factors of all numbers are

Prime factors of 687 are 3 x 229

Prime factors of 268 are 2 x 2 x 67

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

Prime factors of 681 are 3 x 227

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

Given numbers are 687, 268, 980, 681

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

Apply this formula for all numbers.

Step1:

LCM(687, 268) = 184116

GCD(687, 268) = ( 687 x 268 ) / 184116

= 687 / 268

= 687

Step2:

LCM(1, 980) = 980

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

= 1 / 980

= 1

Step3:

LCM(1, 681) = 681

GCD(1, 681) = ( 1 x 681 ) / 681

= 1 / 681

= 1

So, Greatest Common Divisor of 687, 268, 980, 681 is 1
