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

Apply this formula for all numbers.

Step1:

LCM(392, 164) = 16072

GCD(392, 164) = ( 392 x 164 ) / 16072

= 392 / 164

= 392

Step2:

LCM(4, 618) = 1236

GCD(4, 618) = ( 4 x 618 ) / 1236

= 4 / 618

= 4

Step3:

LCM(2, 630) = 630

GCD(2, 630) = ( 2 x 630 ) / 630

= 2 / 630

= 2

So, Greatest Common Divisor of 392, 164, 618, 630 is 2
