We found the divisors of 25, 615, 610, 117 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 25, 615, 610, 117 is 1.

Therefore, GCD of numbers 25, 615, 610, 117 is 1

Given Input Data is 25, 615, 610, 117

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

Prime Factorization of 25 is 5 x 5

Prime Factorization of 615 is 3 x 5 x 41

Prime Factorization of 610 is 2 x 5 x 61

Prime Factorization of 117 is 3 x 3 x 13

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(25, 615) = 3075

GCD(25, 615) = ( 25 x 615 ) / 3075

GCD(25, 615) = 15375 / 3075

GCD(25, 615) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 610

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

LCM(5, 610) = 610

GCD(5, 610) = ( 5 x 610 ) / 610

GCD(5, 610) = 3050 / 610

GCD(5, 610) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 117

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

LCM(5, 117) = 585

GCD(5, 117) = ( 5 x 117 ) / 585

GCD(5, 117) = 585 / 585

GCD(5, 117) = 1

GCD of 25, 615, 610, 117 is 1
