Greatest Common Divisior

We found the divisors of 70, 58, 47, 61 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 70, 58, 47, 61 is 1.

Therefore, GCD of numbers 70, 58, 47, 61 is 1

Given Input Data is 70, 58, 47, 61

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

Prime Factorization of 70 is 2 x 5 x 7

Prime Factorization of 58 is 2 x 29

Prime Factorization of 47 is 47

Prime Factorization of 61 is 61

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(70, 58) = 2030

GCD(70, 58) = ( 70 x 58 ) / 2030

GCD(70, 58) = 4060 / 2030

GCD(70, 58) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 47

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

LCM(2, 47) = 94

GCD(2, 47) = ( 2 x 47 ) / 94

GCD(2, 47) = 94 / 94

GCD(2, 47) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 61

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

LCM(1, 61) = 61

GCD(1, 61) = ( 1 x 61 ) / 61

GCD(1, 61) = 61 / 61

GCD(1, 61) = 1

GCD of 70, 58, 47, 61 is 1
