Given numbers are 617, 646, 681, 871

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

Apply this formula for all numbers.

Step1:

LCM(617, 646) = 398582

GCD(617, 646) = ( 617 x 646 ) / 398582

= 617 / 646

= 617

Step2:

LCM(1, 681) = 681

GCD(1, 681) = ( 1 x 681 ) / 681

= 1 / 681

= 1

Step3:

LCM(1, 871) = 871

GCD(1, 871) = ( 1 x 871 ) / 871

= 1 / 871

= 1

So, Greatest Common Divisor of 617, 646, 681, 871 is 1
