Therefore, GCD of numbers 861, 903, 25, 946 is 1

Given Input Data is 861, 903, 25, 946

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

Prime Factorization of 861 is 3 x 7 x 41

Prime Factorization of 903 is 3 x 7 x 43

Prime Factorization of 25 is 5 x 5

Prime Factorization of 946 is 2 x 11 x 43

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(861, 903) = 37023

GCD(861, 903) = ( 861 x 903 ) / 37023

GCD(861, 903) = 777483 / 37023

GCD(861, 903) = 21

Step2:

Here we consider the GCD from the above i.e. 21 as first number and the next as 25

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

LCM(21, 25) = 525

GCD(21, 25) = ( 21 x 25 ) / 525

GCD(21, 25) = 525 / 525

GCD(21, 25) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 946

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

LCM(1, 946) = 946

GCD(1, 946) = ( 1 x 946 ) / 946

GCD(1, 946) = 946 / 946

GCD(1, 946) = 1

GCD of 861, 903, 25, 946 is 1
