We found the divisors of 84, 13, 74, 98 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 84, 13, 74, 98 is 1.

Therefore, GCD of numbers 84, 13, 74, 98 is 1

Given Input Data is 84, 13, 74, 98

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

Prime Factorization of 84 is 2 x 2 x 3 x 7

Prime Factorization of 13 is 13

Prime Factorization of 74 is 2 x 37

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(84, 13) = 1092

GCD(84, 13) = ( 84 x 13 ) / 1092

GCD(84, 13) = 1092 / 1092

GCD(84, 13) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 74

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

LCM(1, 74) = 74

GCD(1, 74) = ( 1 x 74 ) / 74

GCD(1, 74) = 74 / 74

GCD(1, 74) = 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 84, 13, 74, 98 is 1
