Given numbers are 137, 221, 128

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

Apply this formula for all numbers.

Step1:

LCM(137, 221) = 30277

GCD(137, 221) = ( 137 x 221 ) / 30277

= 137 / 221

= 137

Step2:

LCM(1, 128) = 128

GCD(1, 128) = ( 1 x 128 ) / 128

= 1 / 128

= 1

So, Greatest Common Divisor of 137, 221, 128 is 1
