We found the divisors of 98, 19, 57, 70 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 98, 19, 57, 70 is 1.

Therefore, GCD of numbers 98, 19, 57, 70 is 1

Given Input Data is 98, 19, 57, 70

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

Prime Factorization of 98 is 2 x 7 x 7

Prime Factorization of 19 is 19

Prime Factorization of 57 is 3 x 19

Prime Factorization of 70 is 2 x 5 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(98, 19) = 1862

GCD(98, 19) = ( 98 x 19 ) / 1862

GCD(98, 19) = 1862 / 1862

GCD(98, 19) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 57

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

LCM(1, 57) = 57

GCD(1, 57) = ( 1 x 57 ) / 57

GCD(1, 57) = 57 / 57

GCD(1, 57) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 70

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

LCM(1, 70) = 70

GCD(1, 70) = ( 1 x 70 ) / 70

GCD(1, 70) = 70 / 70

GCD(1, 70) = 1

GCD of 98, 19, 57, 70 is 1
