Given numbers are 642, 610, 82

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

Apply this formula for all numbers.

Step1:

LCM(642, 610) = 195810

GCD(642, 610) = ( 642 x 610 ) / 195810

= 642 / 610

= 642

Step2:

LCM(2, 82) = 82

GCD(2, 82) = ( 2 x 82 ) / 82

= 2 / 82

= 2

So, Greatest Common Divisor of 642, 610, 82 is 2
