Given numbers are 642, 130, 506, 410

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

Apply this formula for all numbers.

Step1:

LCM(642, 130) = 41730

GCD(642, 130) = ( 642 x 130 ) / 41730

= 642 / 130

= 642

Step2:

LCM(2, 506) = 506

GCD(2, 506) = ( 2 x 506 ) / 506

= 2 / 506

= 2

Step3:

LCM(2, 410) = 410

GCD(2, 410) = ( 2 x 410 ) / 410

= 2 / 410

= 2

So, Greatest Common Divisor of 642, 130, 506, 410 is 2
