Steps to Calculate GCD of 403, 398, 109, 154 using LCM Formula
Given numbers are 403, 398, 109, 154
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(403, 398) = 160394
GCD(403, 398) = ( 403 x 398 ) / 160394
= 403 / 398
= 403
Step2:
LCM(1, 109) = 109
GCD(1, 109) = ( 1 x 109 ) / 109
= 1 / 109
= 1
Step3:
LCM(1, 154) = 154
GCD(1, 154) = ( 1 x 154 ) / 154
= 1 / 154
= 1
So, Greatest Common Divisor of 403, 398, 109, 154 is 1
