Given numbers are 690, 657, 897, 956

The list of prime factors of all numbers are

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

Prime factors of 657 are 3 x 3 x 73

Prime factors of 897 are 3 x 13 x 23

Prime factors of 956 are 2 x 2 x 239

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

Given numbers are 690, 657, 897, 956

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

Apply this formula for all numbers.

Step1:

LCM(690, 657) = 151110

GCD(690, 657) = ( 690 x 657 ) / 151110

= 690 / 657

= 690

Step2:

LCM(3, 897) = 897

GCD(3, 897) = ( 3 x 897 ) / 897

= 3 / 897

= 3

Step3:

LCM(3, 956) = 2868

GCD(3, 956) = ( 3 x 956 ) / 2868

= 3 / 956

= 3

So, Greatest Common Divisor of 690, 657, 897, 956 is 1
