Given numbers are 656, 371, 801, 690

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 371 are 7 x 53

Prime factors of 801 are 3 x 3 x 89

Prime factors of 690 are 2 x 3 x 5 x 23

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

Given numbers are 656, 371, 801, 690

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

Apply this formula for all numbers.

Step1:

LCM(656, 371) = 243376

GCD(656, 371) = ( 656 x 371 ) / 243376

= 656 / 371

= 656

Step2:

LCM(1, 801) = 801

GCD(1, 801) = ( 1 x 801 ) / 801

= 1 / 801

= 1

Step3:

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

= 1 / 690

= 1

So, Greatest Common Divisor of 656, 371, 801, 690 is 1
