Therefore, GCD of numbers 636, 540, 155, 378 is 1

Given Input Data is 636, 540, 155, 378

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

Prime Factorization of 636 is 2 x 2 x 3 x 53

Prime Factorization of 540 is 2 x 2 x 3 x 3 x 3 x 5

Prime Factorization of 155 is 5 x 31

Prime Factorization of 378 is 2 x 3 x 3 x 3 x 7

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(636, 540) = 28620

GCD(636, 540) = ( 636 x 540 ) / 28620

GCD(636, 540) = 343440 / 28620

GCD(636, 540) = 12

Step2:

Here we consider the GCD from the above i.e. 12 as first number and the next as 155

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

LCM(12, 155) = 1860

GCD(12, 155) = ( 12 x 155 ) / 1860

GCD(12, 155) = 1860 / 1860

GCD(12, 155) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 378

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

LCM(1, 378) = 378

GCD(1, 378) = ( 1 x 378 ) / 378

GCD(1, 378) = 378 / 378

GCD(1, 378) = 1

GCD of 636, 540, 155, 378 is 1
