Given numbers are 681, 342, 678, 988

The list of prime factors of all numbers are

Prime factors of 681 are 3 x 227

Prime factors of 342 are 2 x 3 x 3 x 19

Prime factors of 678 are 2 x 3 x 113

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

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

Given numbers are 681, 342, 678, 988

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

Apply this formula for all numbers.

Step1:

LCM(681, 342) = 77634

GCD(681, 342) = ( 681 x 342 ) / 77634

= 681 / 342

= 681

Step2:

LCM(3, 678) = 678

GCD(3, 678) = ( 3 x 678 ) / 678

= 3 / 678

= 3

Step3:

LCM(3, 988) = 2964

GCD(3, 988) = ( 3 x 988 ) / 2964

= 3 / 988

= 3

So, Greatest Common Divisor of 681, 342, 678, 988 is 1
