Given numbers are 687, 628, 140, 641

The list of prime factors of all numbers are

Prime factors of 687 are 3 x 229

Prime factors of 628 are 2 x 2 x 157

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

Prime factors of 641 are 641

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

Given numbers are 687, 628, 140, 641

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

Apply this formula for all numbers.

Step1:

LCM(687, 628) = 431436

GCD(687, 628) = ( 687 x 628 ) / 431436

= 687 / 628

= 687

Step2:

LCM(1, 140) = 140

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

= 1 / 140

= 1

Step3:

LCM(1, 641) = 641

GCD(1, 641) = ( 1 x 641 ) / 641

= 1 / 641

= 1

So, Greatest Common Divisor of 687, 628, 140, 641 is 1
