Steps to Calculate GCD of 403, 212, 138, 491 using LCM Formula
Given numbers are 403, 212, 138, 491
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(403, 212) = 85436
GCD(403, 212) = ( 403 x 212 ) / 85436
= 403 / 212
= 403
Step2:
LCM(1, 138) = 138
GCD(1, 138) = ( 1 x 138 ) / 138
= 1 / 138
= 1
Step3:
LCM(1, 491) = 491
GCD(1, 491) = ( 1 x 491 ) / 491
= 1 / 491
= 1
So, Greatest Common Divisor of 403, 212, 138, 491 is 1
