Given numbers are 688, 908, 680, 213

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 908 are 2 x 2 x 227

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

Prime factors of 213 are 3 x 71

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

Given numbers are 688, 908, 680, 213

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

Apply this formula for all numbers.

Step1:

LCM(688, 908) = 156176

GCD(688, 908) = ( 688 x 908 ) / 156176

= 688 / 908

= 688

Step2:

LCM(4, 680) = 680

GCD(4, 680) = ( 4 x 680 ) / 680

= 4 / 680

= 4

Step3:

LCM(4, 213) = 852

GCD(4, 213) = ( 4 x 213 ) / 852

= 4 / 213

= 4

So, Greatest Common Divisor of 688, 908, 680, 213 is 1
