Steps to Calculate GCD of 401, 238, 645, 778 using LCM Formula
Given numbers are 401, 238, 645, 778
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(401, 238) = 95438
GCD(401, 238) = ( 401 x 238 ) / 95438
= 401 / 238
= 401
Step2:
LCM(1, 645) = 645
GCD(1, 645) = ( 1 x 645 ) / 645
= 1 / 645
= 1
Step3:
LCM(1, 778) = 778
GCD(1, 778) = ( 1 x 778 ) / 778
= 1 / 778
= 1
So, Greatest Common Divisor of 401, 238, 645, 778 is 1
