Given numbers are 217, 681, 627, 657

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

Apply this formula for all numbers.

Step1:

LCM(217, 681) = 147777

GCD(217, 681) = ( 217 x 681 ) / 147777

= 217 / 681

= 217

Step2:

LCM(1, 627) = 627

GCD(1, 627) = ( 1 x 627 ) / 627

= 1 / 627

= 1

Step3:

LCM(1, 657) = 657

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

= 1 / 657

= 1

So, Greatest Common Divisor of 217, 681, 627, 657 is 1
