Steps to Calculate GCD of 403, 311, 490, 129 using LCM Formula
Given numbers are 403, 311, 490, 129
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(403, 311) = 125333
GCD(403, 311) = ( 403 x 311 ) / 125333
= 403 / 311
= 403
Step2:
LCM(1, 490) = 490
GCD(1, 490) = ( 1 x 490 ) / 490
= 1 / 490
= 1
Step3:
LCM(1, 129) = 129
GCD(1, 129) = ( 1 x 129 ) / 129
= 1 / 129
= 1
So, Greatest Common Divisor of 403, 311, 490, 129 is 1
