Given numbers are 644, 686, 617, 101

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

Apply this formula for all numbers.

Step1:

LCM(644, 686) = 31556

GCD(644, 686) = ( 644 x 686 ) / 31556

= 644 / 686

= 644

Step2:

LCM(14, 617) = 8638

GCD(14, 617) = ( 14 x 617 ) / 8638

= 14 / 617

= 14

Step3:

LCM(1, 101) = 101

GCD(1, 101) = ( 1 x 101 ) / 101

= 1 / 101

= 1

So, Greatest Common Divisor of 644, 686, 617, 101 is 1
