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

Apply this formula for all numbers.

Step1:

LCM(643, 327) = 210261

GCD(643, 327) = ( 643 x 327 ) / 210261

= 643 / 327

= 643

Step2:

LCM(1, 162) = 162

GCD(1, 162) = ( 1 x 162 ) / 162

= 1 / 162

= 1

So, Greatest Common Divisor of 643, 327, 162 is 1
