Given numbers are 468, 645, 688, 254

The list of prime factors of all numbers are

Prime factors of 468 are 2 x 2 x 3 x 3 x 13

Prime factors of 645 are 3 x 5 x 43

Prime factors of 688 are 2 x 2 x 2 x 2 x 43

Prime factors of 254 are 2 x 127

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

Given numbers are 468, 645, 688, 254

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

Apply this formula for all numbers.

Step1:

LCM(468, 645) = 100620

GCD(468, 645) = ( 468 x 645 ) / 100620

= 468 / 645

= 468

Step2:

LCM(3, 688) = 2064

GCD(3, 688) = ( 3 x 688 ) / 2064

= 3 / 688

= 3

Step3:

LCM(1, 254) = 254

GCD(1, 254) = ( 1 x 254 ) / 254

= 1 / 254

= 1

So, Greatest Common Divisor of 468, 645, 688, 254 is 1
