Therefore, GCD of numbers 141, 210, 408 is 3

Given Input Data is 141, 210, 408

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 141 is 3 x 47

Prime Factorization of 210 is 2 x 3 x 5 x 7

Prime Factorization of 408 is 2 x 2 x 2 x 3 x 17

Highest common occurrences in the given inputs are 3¹

Multiplying them we get the GCD as 3

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(141, 210) = 9870

GCD(141, 210) = ( 141 x 210 ) / 9870

GCD(141, 210) = 29610 / 9870

GCD(141, 210) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 408

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(3, 408) = 408

GCD(3, 408) = ( 3 x 408 ) / 408

GCD(3, 408) = 1224 / 408

GCD(3, 408) = 3

GCD of 141, 210, 408 is 3
