Given numbers are 688, 721, 707, 936

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 721 are 7 x 103

Prime factors of 707 are 7 x 101

Prime factors of 936 are 2 x 2 x 2 x 3 x 3 x 13

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

Given numbers are 688, 721, 707, 936

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

Apply this formula for all numbers.

Step1:

LCM(688, 721) = 496048

GCD(688, 721) = ( 688 x 721 ) / 496048

= 688 / 721

= 688

Step2:

LCM(1, 707) = 707

GCD(1, 707) = ( 1 x 707 ) / 707

= 1 / 707

= 1

Step3:

LCM(1, 936) = 936

GCD(1, 936) = ( 1 x 936 ) / 936

= 1 / 936

= 1

So, Greatest Common Divisor of 688, 721, 707, 936 is 1
