Given numbers are 660, 968, 980, 642

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

Apply this formula for all numbers.

Step1:

LCM(660, 968) = 14520

GCD(660, 968) = ( 660 x 968 ) / 14520

= 660 / 968

= 660

Step2:

LCM(44, 980) = 10780

GCD(44, 980) = ( 44 x 980 ) / 10780

= 44 / 980

= 44

Step3:

LCM(4, 642) = 1284

GCD(4, 642) = ( 4 x 642 ) / 1284

= 4 / 642

= 4

So, Greatest Common Divisor of 660, 968, 980, 642 is 2
