Given numbers are 988, 688, 656, 189

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

Apply this formula for all numbers.

Step1:

LCM(988, 688) = 169936

GCD(988, 688) = ( 988 x 688 ) / 169936

= 988 / 688

= 988

Step2:

LCM(4, 656) = 656

GCD(4, 656) = ( 4 x 656 ) / 656

= 4 / 656

= 4

Step3:

LCM(4, 189) = 756

GCD(4, 189) = ( 4 x 189 ) / 756

= 4 / 189

= 4

So, Greatest Common Divisor of 988, 688, 656, 189 is 1
