Given numbers are 687, 775, 312, 458

The list of prime factors of all numbers are

Prime factors of 687 are 3 x 229

Prime factors of 775 are 5 x 5 x 31

Prime factors of 312 are 2 x 2 x 2 x 3 x 13

Prime factors of 458 are 2 x 229

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

Given numbers are 687, 775, 312, 458

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

Apply this formula for all numbers.

Step1:

LCM(687, 775) = 532425

GCD(687, 775) = ( 687 x 775 ) / 532425

= 687 / 775

= 687

Step2:

LCM(1, 312) = 312

GCD(1, 312) = ( 1 x 312 ) / 312

= 1 / 312

= 1

Step3:

LCM(1, 458) = 458

GCD(1, 458) = ( 1 x 458 ) / 458

= 1 / 458

= 1

So, Greatest Common Divisor of 687, 775, 312, 458 is 1
