Given numbers are 137, 643, 120, 163

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

Apply this formula for all numbers.

Step1:

LCM(137, 643) = 88091

GCD(137, 643) = ( 137 x 643 ) / 88091

= 137 / 643

= 137

Step2:

LCM(1, 120) = 120

GCD(1, 120) = ( 1 x 120 ) / 120

= 1 / 120

= 1

Step3:

LCM(1, 163) = 163

GCD(1, 163) = ( 1 x 163 ) / 163

= 1 / 163

= 1

So, Greatest Common Divisor of 137, 643, 120, 163 is 1
