Given numbers are 656, 378, 749, 826

The list of prime factors of all numbers are

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

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

Prime factors of 749 are 7 x 107

Prime factors of 826 are 2 x 7 x 59

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

Given numbers are 656, 378, 749, 826

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

Apply this formula for all numbers.

Step1:

LCM(656, 378) = 123984

GCD(656, 378) = ( 656 x 378 ) / 123984

= 656 / 378

= 656

Step2:

LCM(2, 749) = 1498

GCD(2, 749) = ( 2 x 749 ) / 1498

= 2 / 749

= 2

Step3:

LCM(1, 826) = 826

GCD(1, 826) = ( 1 x 826 ) / 826

= 1 / 826

= 1

So, Greatest Common Divisor of 656, 378, 749, 826 is 1
