Given numbers are 688, 456, 149, 286

The list of prime factors of all numbers are

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

Prime factors of 456 are 2 x 2 x 2 x 3 x 19

Prime factors of 149 are 149

Prime factors of 286 are 2 x 11 x 13

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

Given numbers are 688, 456, 149, 286

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

Apply this formula for all numbers.

Step1:

LCM(688, 456) = 39216

GCD(688, 456) = ( 688 x 456 ) / 39216

= 688 / 456

= 688

Step2:

LCM(8, 149) = 1192

GCD(8, 149) = ( 8 x 149 ) / 1192

= 8 / 149

= 8

Step3:

LCM(1, 286) = 286

GCD(1, 286) = ( 1 x 286 ) / 286

= 1 / 286

= 1

So, Greatest Common Divisor of 688, 456, 149, 286 is 1
