Steps to Calculate GCD of 649, 813, 645, 238 using LCM Formula
Given numbers are 649, 813, 645, 238
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(649, 813) = 527637
GCD(649, 813) = ( 649 x 813 ) / 527637
= 649 / 813
= 649
Step2:
LCM(1, 645) = 645
GCD(1, 645) = ( 1 x 645 ) / 645
= 1 / 645
= 1
Step3:
LCM(1, 238) = 238
GCD(1, 238) = ( 1 x 238 ) / 238
= 1 / 238
= 1
So, Greatest Common Divisor of 649, 813, 645, 238 is 1
