We found the divisors of 851, 130, 143, 903 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 851, 130, 143, 903 is 1.

Therefore, GCD of numbers 851, 130, 143, 903 is 1

Given Input Data is 851, 130, 143, 903

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

Prime Factorization of 851 is 23 x 37

Prime Factorization of 130 is 2 x 5 x 13

Prime Factorization of 143 is 11 x 13

Prime Factorization of 903 is 3 x 7 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(851, 130) = 110630

GCD(851, 130) = ( 851 x 130 ) / 110630

GCD(851, 130) = 110630 / 110630

GCD(851, 130) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 143

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

LCM(1, 143) = 143

GCD(1, 143) = ( 1 x 143 ) / 143

GCD(1, 143) = 143 / 143

GCD(1, 143) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 903

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

LCM(1, 903) = 903

GCD(1, 903) = ( 1 x 903 ) / 903

GCD(1, 903) = 903 / 903

GCD(1, 903) = 1

GCD of 851, 130, 143, 903 is 1
