Therefore, GCD of numbers 606, 990, 637, 144 is 1

Given Input Data is 606, 990, 637, 144

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

Prime Factorization of 606 is 2 x 3 x 101

Prime Factorization of 990 is 2 x 3 x 3 x 5 x 11

Prime Factorization of 637 is 7 x 7 x 13

Prime Factorization of 144 is 2 x 2 x 2 x 2 x 3 x 3

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(606, 990) = 99990

GCD(606, 990) = ( 606 x 990 ) / 99990

GCD(606, 990) = 599940 / 99990

GCD(606, 990) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 637

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

LCM(6, 637) = 3822

GCD(6, 637) = ( 6 x 637 ) / 3822

GCD(6, 637) = 3822 / 3822

GCD(6, 637) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 144

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

LCM(1, 144) = 144

GCD(1, 144) = ( 1 x 144 ) / 144

GCD(1, 144) = 144 / 144

GCD(1, 144) = 1

GCD of 606, 990, 637, 144 is 1
