Greatest Common Divisior

We found the divisors of 94, 21, 25 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 94, 21, 25 is 1.

Therefore, GCD of numbers 94, 21, 25 is 1

Given Input Data is 94, 21, 25

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

Prime Factorization of 94 is 2 x 47

Prime Factorization of 21 is 3 x 7

Prime Factorization of 25 is 5 x 5

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(94, 21) = 1974

GCD(94, 21) = ( 94 x 21 ) / 1974

GCD(94, 21) = 1974 / 1974

GCD(94, 21) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 25

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

LCM(1, 25) = 25

GCD(1, 25) = ( 1 x 25 ) / 25

GCD(1, 25) = 25 / 25

GCD(1, 25) = 1

GCD of 94, 21, 25 is 1
