Greatest Common Divisior

We found the divisors of 60, 44, 25, 15 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 60, 44, 25, 15 is 1.

Therefore, GCD of numbers 60, 44, 25, 15 is 1

Given Input Data is 60, 44, 25, 15

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

Prime Factorization of 60 is 2 x 2 x 3 x 5

Prime Factorization of 44 is 2 x 2 x 11

Prime Factorization of 25 is 5 x 5

Prime Factorization of 15 is 3 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(60, 44) = 660

GCD(60, 44) = ( 60 x 44 ) / 660

GCD(60, 44) = 2640 / 660

GCD(60, 44) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 25

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

LCM(4, 25) = 100

GCD(4, 25) = ( 4 x 25 ) / 100

GCD(4, 25) = 100 / 100

GCD(4, 25) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 15

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

LCM(1, 15) = 15

GCD(1, 15) = ( 1 x 15 ) / 15

GCD(1, 15) = 15 / 15

GCD(1, 15) = 1

GCD of 60, 44, 25, 15 is 1
