Given numbers are 688, 115, 684, 906

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 115 are 5 x 23

Prime factors of 684 are 2 x 2 x 3 x 3 x 19

Prime factors of 906 are 2 x 3 x 151

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

Given numbers are 688, 115, 684, 906

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

Apply this formula for all numbers.

Step1:

LCM(688, 115) = 79120

GCD(688, 115) = ( 688 x 115 ) / 79120

= 688 / 115

= 688

Step2:

LCM(1, 684) = 684

GCD(1, 684) = ( 1 x 684 ) / 684

= 1 / 684

= 1

Step3:

LCM(1, 906) = 906

GCD(1, 906) = ( 1 x 906 ) / 906

= 1 / 906

= 1

So, Greatest Common Divisor of 688, 115, 684, 906 is 1
