We found the divisors of 98, 77, 75 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 98, 77, 75 is 1.

Therefore, GCD of numbers 98, 77, 75 is 1

Given Input Data is 98, 77, 75

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 77 is 7 x 11

Prime Factorization of 75 is 3 x 5 x 5

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, 77) = 1078

GCD(98, 77) = ( 98 x 77 ) / 1078

GCD(98, 77) = 7546 / 1078

GCD(98, 77) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 75

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

LCM(7, 75) = 525

GCD(7, 75) = ( 7 x 75 ) / 525

GCD(7, 75) = 525 / 525

GCD(7, 75) = 1

GCD of 98, 77, 75 is 1
