We found the divisors of 98, 69, 67, 55 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 98, 69, 67, 55 is 1.

Therefore, GCD of numbers 98, 69, 67, 55 is 1

Given Input Data is 98, 69, 67, 55

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 69 is 3 x 23

Prime Factorization of 67 is 67

Prime Factorization of 55 is 5 x 11

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, 69) = 6762

GCD(98, 69) = ( 98 x 69 ) / 6762

GCD(98, 69) = 6762 / 6762

GCD(98, 69) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 67

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

LCM(1, 67) = 67

GCD(1, 67) = ( 1 x 67 ) / 67

GCD(1, 67) = 67 / 67

GCD(1, 67) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 55

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

LCM(1, 55) = 55

GCD(1, 55) = ( 1 x 55 ) / 55

GCD(1, 55) = 55 / 55

GCD(1, 55) = 1

GCD of 98, 69, 67, 55 is 1
