Given numbers are 686, 272, 29, 102

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

Apply this formula for all numbers.

Step1:

LCM(686, 272) = 93296

GCD(686, 272) = ( 686 x 272 ) / 93296

= 686 / 272

= 686

Step2:

LCM(2, 29) = 58

GCD(2, 29) = ( 2 x 29 ) / 58

= 2 / 29

= 2

Step3:

LCM(1, 102) = 102

GCD(1, 102) = ( 1 x 102 ) / 102

= 1 / 102

= 1

So, Greatest Common Divisor of 686, 272, 29, 102 is 1
