Therefore, GCD of numbers 801, 780, 15, 976 is 1

Given Input Data is 801, 780, 15, 976

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

Prime Factorization of 801 is 3 x 3 x 89

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

Prime Factorization of 15 is 3 x 5

Prime Factorization of 976 is 2 x 2 x 2 x 2 x 61

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(801, 780) = 208260

GCD(801, 780) = ( 801 x 780 ) / 208260

GCD(801, 780) = 624780 / 208260

GCD(801, 780) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 15

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

LCM(3, 15) = 15

GCD(3, 15) = ( 3 x 15 ) / 15

GCD(3, 15) = 45 / 15

GCD(3, 15) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 976

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

LCM(3, 976) = 2928

GCD(3, 976) = ( 3 x 976 ) / 2928

GCD(3, 976) = 2928 / 2928

GCD(3, 976) = 1

GCD of 801, 780, 15, 976 is 1
