Given numbers are 662, 662, 646, 198

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

Apply this formula for all numbers.

Step1:

LCM(662, 662) = 662

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

= 662 / 662

= 662

Step2:

LCM(662, 646) = 213826

GCD(662, 646) = ( 662 x 646 ) / 213826

= 662 / 646

= 662

Step3:

LCM(2, 198) = 198

GCD(2, 198) = ( 2 x 198 ) / 198

= 2 / 198

= 2

So, Greatest Common Divisor of 662, 662, 646, 198 is 2
