Given numbers are 621, 168, 102

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

Apply this formula for all numbers.

Step1:

LCM(621, 168) = 34776

GCD(621, 168) = ( 621 x 168 ) / 34776

= 621 / 168

= 621

Step2:

LCM(3, 102) = 102

GCD(3, 102) = ( 3 x 102 ) / 102

= 3 / 102

= 3

So, Greatest Common Divisor of 621, 168, 102 is 3
