Given numbers are 476, 612, 18, 642

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

Apply this formula for all numbers.

Step1:

LCM(476, 612) = 4284

GCD(476, 612) = ( 476 x 612 ) / 4284

= 476 / 612

= 476

Step2:

LCM(68, 18) = 612

GCD(68, 18) = ( 68 x 18 ) / 612

= 68 / 18

= 68

Step3:

LCM(2, 642) = 642

GCD(2, 642) = ( 2 x 642 ) / 642

= 2 / 642

= 2

So, Greatest Common Divisor of 476, 612, 18, 642 is 2
