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

Apply this formula for all numbers.

Step1:

LCM(662, 398) = 131738

GCD(662, 398) = ( 662 x 398 ) / 131738

= 662 / 398

= 662

Step2:

LCM(2, 862) = 862

GCD(2, 862) = ( 2 x 862 ) / 862

= 2 / 862

= 2

Step3:

LCM(2, 128) = 128

GCD(2, 128) = ( 2 x 128 ) / 128

= 2 / 128

= 2

So, Greatest Common Divisor of 662, 398, 862, 128 is 2
