We found the divisors of 643, 725, 140, 955 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 643, 725, 140, 955 is 1.

Therefore, GCD of numbers 643, 725, 140, 955 is 1

Given Input Data is 643, 725, 140, 955

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

Prime Factorization of 643 is 643

Prime Factorization of 725 is 5 x 5 x 29

Prime Factorization of 140 is 2 x 2 x 5 x 7

Prime Factorization of 955 is 5 x 191

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(643, 725) = 466175

GCD(643, 725) = ( 643 x 725 ) / 466175

GCD(643, 725) = 466175 / 466175

GCD(643, 725) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 140

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

LCM(1, 140) = 140

GCD(1, 140) = ( 1 x 140 ) / 140

GCD(1, 140) = 140 / 140

GCD(1, 140) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 955

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

LCM(1, 955) = 955

GCD(1, 955) = ( 1 x 955 ) / 955

GCD(1, 955) = 955 / 955

GCD(1, 955) = 1

GCD of 643, 725, 140, 955 is 1
