Given numbers are 681, 556, 203, 140

The list of prime factors of all numbers are

Prime factors of 681 are 3 x 227

Prime factors of 556 are 2 x 2 x 139

Prime factors of 203 are 7 x 29

Prime factors of 140 are 2 x 2 x 5 x 7

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

Given numbers are 681, 556, 203, 140

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

Apply this formula for all numbers.

Step1:

LCM(681, 556) = 378636

GCD(681, 556) = ( 681 x 556 ) / 378636

= 681 / 556

= 681

Step2:

LCM(1, 203) = 203

GCD(1, 203) = ( 1 x 203 ) / 203

= 1 / 203

= 1

Step3:

LCM(1, 140) = 140

GCD(1, 140) = ( 1 x 140 ) / 140

= 1 / 140

= 1

So, Greatest Common Divisor of 681, 556, 203, 140 is 1
