Given numbers are 690, 252, 289, 657

The list of prime factors of all numbers are

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

Prime factors of 252 are 2 x 2 x 3 x 3 x 7

Prime factors of 289 are 17 x 17

Prime factors of 657 are 3 x 3 x 73

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

Given numbers are 690, 252, 289, 657

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

Apply this formula for all numbers.

Step1:

LCM(690, 252) = 28980

GCD(690, 252) = ( 690 x 252 ) / 28980

= 690 / 252

= 690

Step2:

LCM(6, 289) = 1734

GCD(6, 289) = ( 6 x 289 ) / 1734

= 6 / 289

= 6

Step3:

LCM(1, 657) = 657

GCD(1, 657) = ( 1 x 657 ) / 657

= 1 / 657

= 1

So, Greatest Common Divisor of 690, 252, 289, 657 is 1
