Therefore, GCD of numbers 610, 140, 30, 903 is 1

Given Input Data is 610, 140, 30, 903

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

Prime Factorization of 610 is 2 x 5 x 61

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

Prime Factorization of 30 is 2 x 3 x 5

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(610, 140) = 8540

GCD(610, 140) = ( 610 x 140 ) / 8540

GCD(610, 140) = 85400 / 8540

GCD(610, 140) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 30

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

LCM(10, 30) = 30

GCD(10, 30) = ( 10 x 30 ) / 30

GCD(10, 30) = 300 / 30

GCD(10, 30) = 10

Step3:

Here we consider the GCD from the above i.e. 10 as first number and the next as 903

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

LCM(10, 903) = 9030

GCD(10, 903) = ( 10 x 903 ) / 9030

GCD(10, 903) = 9030 / 9030

GCD(10, 903) = 1

GCD of 610, 140, 30, 903 is 1
