Given numbers are 686, 623, 22, 549

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

Apply this formula for all numbers.

Step1:

LCM(686, 623) = 61054

GCD(686, 623) = ( 686 x 623 ) / 61054

= 686 / 623

= 686

Step2:

LCM(7, 22) = 154

GCD(7, 22) = ( 7 x 22 ) / 154

= 7 / 22

= 7

Step3:

LCM(1, 549) = 549

GCD(1, 549) = ( 1 x 549 ) / 549

= 1 / 549

= 1

So, Greatest Common Divisor of 686, 623, 22, 549 is 1
