Given numbers are 681, 988, 636, 768

The list of prime factors of all numbers are

Prime factors of 681 are 3 x 227

Prime factors of 988 are 2 x 2 x 13 x 19

Prime factors of 636 are 2 x 2 x 3 x 53

Prime factors of 768 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

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

Given numbers are 681, 988, 636, 768

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

Apply this formula for all numbers.

Step1:

LCM(681, 988) = 672828

GCD(681, 988) = ( 681 x 988 ) / 672828

= 681 / 988

= 681

Step2:

LCM(1, 636) = 636

GCD(1, 636) = ( 1 x 636 ) / 636

= 1 / 636

= 1

Step3:

LCM(1, 768) = 768

GCD(1, 768) = ( 1 x 768 ) / 768

= 1 / 768

= 1

So, Greatest Common Divisor of 681, 988, 636, 768 is 1
