We found the divisors of 58, 31, 15, 98 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 58, 31, 15, 98 is 1.

Therefore, GCD of numbers 58, 31, 15, 98 is 1

Given Input Data is 58, 31, 15, 98

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

Prime Factorization of 58 is 2 x 29

Prime Factorization of 31 is 31

Prime Factorization of 15 is 3 x 5

Prime Factorization of 98 is 2 x 7 x 7

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(58, 31) = 1798

GCD(58, 31) = ( 58 x 31 ) / 1798

GCD(58, 31) = 1798 / 1798

GCD(58, 31) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 15

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

LCM(1, 15) = 15

GCD(1, 15) = ( 1 x 15 ) / 15

GCD(1, 15) = 15 / 15

GCD(1, 15) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 98

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

LCM(1, 98) = 98

GCD(1, 98) = ( 1 x 98 ) / 98

GCD(1, 98) = 98 / 98

GCD(1, 98) = 1

GCD of 58, 31, 15, 98 is 1
