Steps to Calculate GCD of 409, 305, 474, 381 using LCM Formula
Given numbers are 409, 305, 474, 381
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(409, 305) = 124745
GCD(409, 305) = ( 409 x 305 ) / 124745
= 409 / 305
= 409
Step2:
LCM(1, 474) = 474
GCD(1, 474) = ( 1 x 474 ) / 474
= 1 / 474
= 1
Step3:
LCM(1, 381) = 381
GCD(1, 381) = ( 1 x 381 ) / 381
= 1 / 381
= 1
So, Greatest Common Divisor of 409, 305, 474, 381 is 1
