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

Apply this formula for all numbers.

Step1:

LCM(654, 390) = 42510

GCD(654, 390) = ( 654 x 390 ) / 42510

= 654 / 390

= 654

Step2:

LCM(6, 142) = 426

GCD(6, 142) = ( 6 x 142 ) / 426

= 6 / 142

= 6

Step3:

LCM(2, 446) = 446

GCD(2, 446) = ( 2 x 446 ) / 446

= 2 / 446

= 2

So, Greatest Common Divisor of 654, 390, 142, 446 is 2
