Therefore, GCD of numbers 424, 750, 780, 181 is 1

Given Input Data is 424, 750, 780, 181

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

Prime Factorization of 424 is 2 x 2 x 2 x 53

Prime Factorization of 750 is 2 x 3 x 5 x 5 x 5

Prime Factorization of 780 is 2 x 2 x 3 x 5 x 13

Prime Factorization of 181 is 181

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(424, 750) = 159000

GCD(424, 750) = ( 424 x 750 ) / 159000

GCD(424, 750) = 318000 / 159000

GCD(424, 750) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 780

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

LCM(2, 780) = 780

GCD(2, 780) = ( 2 x 780 ) / 780

GCD(2, 780) = 1560 / 780

GCD(2, 780) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 181

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

LCM(2, 181) = 362

GCD(2, 181) = ( 2 x 181 ) / 362

GCD(2, 181) = 362 / 362

GCD(2, 181) = 1

GCD of 424, 750, 780, 181 is 1
