Steps to Calculate GCD of 137, 321, 670, 563 using LCM Formula

Given numbers are 137, 321, 670, 563

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

Apply this formula for all numbers.

Step1:

LCM(137, 321) = 43977

GCD(137, 321) = ( 137 x 321 ) / 43977

= 137 / 321

= 137


Step2:

LCM(1, 670) = 670

GCD(1, 670) = ( 1 x 670 ) / 670

= 1 / 670

= 1


Step3:

LCM(1, 563) = 563

GCD(1, 563) = ( 1 x 563 ) / 563

= 1 / 563

= 1


So, Greatest Common Divisor of 137, 321, 670, 563 is 1
