Given numbers are 687, 691, 132, 636

The list of prime factors of all numbers are

Prime factors of 687 are 3 x 229

Prime factors of 691 are 691

Prime factors of 132 are 2 x 2 x 3 x 11

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

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

Given numbers are 687, 691, 132, 636

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

Apply this formula for all numbers.

Step1:

LCM(687, 691) = 474717

GCD(687, 691) = ( 687 x 691 ) / 474717

= 687 / 691

= 687

Step2:

LCM(1, 132) = 132

GCD(1, 132) = ( 1 x 132 ) / 132

= 1 / 132

= 1

Step3:

LCM(1, 636) = 636

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

= 1 / 636

= 1

So, Greatest Common Divisor of 687, 691, 132, 636 is 1
