Given numbers are 483, 231, 42

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

Apply this formula for all numbers.

Step1:

LCM(483, 231) = 5313

GCD(483, 231) = ( 483 x 231 ) / 5313

= 483 / 231

= 483

Step2:

LCM(21, 42) = 42

GCD(21, 42) = ( 21 x 42 ) / 42

= 21 / 42

= 21

So, Greatest Common Divisor of 483, 231, 42 is 21
