Given numbers are 363, 390, 451, 687

The list of prime factors of all numbers are

Prime factors of 363 are 3 x 11 x 11

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 451 are 11 x 41

Prime factors of 687 are 3 x 229

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

Given numbers are 363, 390, 451, 687

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

Apply this formula for all numbers.

Step1:

LCM(363, 390) = 47190

GCD(363, 390) = ( 363 x 390 ) / 47190

= 363 / 390

= 363

Step2:

LCM(3, 451) = 1353

GCD(3, 451) = ( 3 x 451 ) / 1353

= 3 / 451

= 3

Step3:

LCM(1, 687) = 687

GCD(1, 687) = ( 1 x 687 ) / 687

= 1 / 687

= 1

So, Greatest Common Divisor of 363, 390, 451, 687 is 1
