Therefore, GCD of numbers 143, 156, 411 is 1

Given Input Data is 143, 156, 411

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

Prime Factorization of 143 is 11 x 13

Prime Factorization of 156 is 2 x 2 x 3 x 13

Prime Factorization of 411 is 3 x 137

The above numbers do not have any common prime factor. So GCD is 1

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(143, 156) = 1716

GCD(143, 156) = ( 143 x 156 ) / 1716

GCD(143, 156) = 22308 / 1716

GCD(143, 156) = 13

Step2:

Here we consider the GCD from the above i.e. 13 as first number and the next as 411

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

LCM(13, 411) = 5343

GCD(13, 411) = ( 13 x 411 ) / 5343

GCD(13, 411) = 5343 / 5343

GCD(13, 411) = 1

GCD of 143, 156, 411 is 1
