Given numbers are 616, 686, 569, 645

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

Apply this formula for all numbers.

Step1:

LCM(616, 686) = 30184

GCD(616, 686) = ( 616 x 686 ) / 30184

= 616 / 686

= 616

Step2:

LCM(14, 569) = 7966

GCD(14, 569) = ( 14 x 569 ) / 7966

= 14 / 569

= 14

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 616, 686, 569, 645 is 1
