Given numbers are 137, 987, 188, 657

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

Apply this formula for all numbers.

Step1:

LCM(137, 987) = 135219

GCD(137, 987) = ( 137 x 987 ) / 135219

= 137 / 987

= 137

Step2:

LCM(1, 188) = 188

GCD(1, 188) = ( 1 x 188 ) / 188

= 1 / 188

= 1

Step3:

LCM(1, 657) = 657

GCD(1, 657) = ( 1 x 657 ) / 657

= 1 / 657

= 1

So, Greatest Common Divisor of 137, 987, 188, 657 is 1
