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

Apply this formula for all numbers.

Step1:

LCM(643, 942) = 605706

GCD(643, 942) = ( 643 x 942 ) / 605706

= 643 / 942

= 643

Step2:

LCM(1, 13) = 13

GCD(1, 13) = ( 1 x 13 ) / 13

= 1 / 13

= 1

So, Greatest Common Divisor of 643, 942, 13 is 1
