Given numbers are 289, 425, 653, 657

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

Apply this formula for all numbers.

Step1:

LCM(289, 425) = 7225

GCD(289, 425) = ( 289 x 425 ) / 7225

= 289 / 425

= 289

Step2:

LCM(17, 653) = 11101

GCD(17, 653) = ( 17 x 653 ) / 11101

= 17 / 653

= 17

Step3:

LCM(1, 657) = 657

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

= 1 / 657

= 1

So, Greatest Common Divisor of 289, 425, 653, 657 is 1
