Steps to Calculate GCD of 644, 382, 381, 310 using LCM Formula

Given numbers are 644, 382, 381, 310

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

Apply this formula for all numbers.

Step1:

LCM(644, 382) = 123004

GCD(644, 382) = ( 644 x 382 ) / 123004

= 644 / 382

= 644


Step2:

LCM(2, 381) = 762

GCD(2, 381) = ( 2 x 381 ) / 762

= 2 / 381

= 2


Step3:

LCM(1, 310) = 310

GCD(1, 310) = ( 1 x 310 ) / 310

= 1 / 310

= 1


So, Greatest Common Divisor of 644, 382, 381, 310 is 1
