Given numbers are 687, 102, 346, 451

The list of prime factors of all numbers are

Prime factors of 687 are 3 x 229

Prime factors of 102 are 2 x 3 x 17

Prime factors of 346 are 2 x 173

Prime factors of 451 are 11 x 41

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

Given numbers are 687, 102, 346, 451

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

Apply this formula for all numbers.

Step1:

LCM(687, 102) = 23358

GCD(687, 102) = ( 687 x 102 ) / 23358

= 687 / 102

= 687

Step2:

LCM(3, 346) = 1038

GCD(3, 346) = ( 3 x 346 ) / 1038

= 3 / 346

= 3

Step3:

LCM(1, 451) = 451

GCD(1, 451) = ( 1 x 451 ) / 451

= 1 / 451

= 1

So, Greatest Common Divisor of 687, 102, 346, 451 is 1
