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

Apply this formula for all numbers.

Step1:

LCM(628, 580) = 91060

GCD(628, 580) = ( 628 x 580 ) / 91060

= 628 / 580

= 628

Step2:

LCM(4, 686) = 1372

GCD(4, 686) = ( 4 x 686 ) / 1372

= 4 / 686

= 4

Step3:

LCM(2, 158) = 158

GCD(2, 158) = ( 2 x 158 ) / 158

= 2 / 158

= 2

So, Greatest Common Divisor of 628, 580, 686, 158 is 2
