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

Apply this formula for all numbers.

Step1:

LCM(148, 790) = 58460

GCD(148, 790) = ( 148 x 790 ) / 58460

= 148 / 790

= 148

Step2:

LCM(2, 638) = 638

GCD(2, 638) = ( 2 x 638 ) / 638

= 2 / 638

= 2

Step3:

LCM(2, 386) = 386

GCD(2, 386) = ( 2 x 386 ) / 386

= 2 / 386

= 2

So, Greatest Common Divisor of 148, 790, 638, 386 is 2
