Given numbers are 621, 164, 355

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

Apply this formula for all numbers.

Step1:

LCM(621, 164) = 101844

GCD(621, 164) = ( 621 x 164 ) / 101844

= 621 / 164

= 621

Step2:

LCM(1, 355) = 355

GCD(1, 355) = ( 1 x 355 ) / 355

= 1 / 355

= 1

So, Greatest Common Divisor of 621, 164, 355 is 1
