Therefore, GCD of numbers 212, 244, 755, 400 is 1

Given Input Data is 212, 244, 755, 400

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

Prime Factorization of 212 is 2 x 2 x 53

Prime Factorization of 244 is 2 x 2 x 61

Prime Factorization of 755 is 5 x 151

Prime Factorization of 400 is 2 x 2 x 2 x 2 x 5 x 5

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(212, 244) = 12932

GCD(212, 244) = ( 212 x 244 ) / 12932

GCD(212, 244) = 51728 / 12932

GCD(212, 244) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 755

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

LCM(4, 755) = 3020

GCD(4, 755) = ( 4 x 755 ) / 3020

GCD(4, 755) = 3020 / 3020

GCD(4, 755) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 400

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

LCM(1, 400) = 400

GCD(1, 400) = ( 1 x 400 ) / 400

GCD(1, 400) = 400 / 400

GCD(1, 400) = 1

GCD of 212, 244, 755, 400 is 1
