Given numbers are 255, 174, 378, 688

The list of prime factors of all numbers are

Prime factors of 255 are 3 x 5 x 17

Prime factors of 174 are 2 x 3 x 29

Prime factors of 378 are 2 x 3 x 3 x 3 x 7

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

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

Given numbers are 255, 174, 378, 688

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

Apply this formula for all numbers.

Step1:

LCM(255, 174) = 14790

GCD(255, 174) = ( 255 x 174 ) / 14790

= 255 / 174

= 255

Step2:

LCM(3, 378) = 378

GCD(3, 378) = ( 3 x 378 ) / 378

= 3 / 378

= 3

Step3:

LCM(3, 688) = 2064

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

= 3 / 688

= 3

So, Greatest Common Divisor of 255, 174, 378, 688 is 1
