Therefore, GCD of numbers 15, 978, 143, 933 is 1

Given Input Data is 15, 978, 143, 933

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

Prime Factorization of 15 is 3 x 5

Prime Factorization of 978 is 2 x 3 x 163

Prime Factorization of 143 is 11 x 13

Prime Factorization of 933 is 3 x 311

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(15, 978) = 4890

GCD(15, 978) = ( 15 x 978 ) / 4890

GCD(15, 978) = 14670 / 4890

GCD(15, 978) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 143

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

LCM(3, 143) = 429

GCD(3, 143) = ( 3 x 143 ) / 429

GCD(3, 143) = 429 / 429

GCD(3, 143) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 933

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

LCM(1, 933) = 933

GCD(1, 933) = ( 1 x 933 ) / 933

GCD(1, 933) = 933 / 933

GCD(1, 933) = 1

GCD of 15, 978, 143, 933 is 1
