Greatest Common Divisior
We found the divisors of 98, 7, 84, 85 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 98, 7, 84, 85 is 1.
Therefore, GCD of numbers 98, 7, 84, 85 is 1
Given Input Data is 98, 7, 84, 85
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 7 is 7
Prime Factorization of 84 is 2 x 2 x 3 x 7
Prime Factorization of 85 is 5 x 17
The above numbers do not have any common prime factor. So GCD is 1
Finding GCD of 98, 7, 84, 85 using LCM Formula
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, 7) = 98
GCD(98, 7) = ( 98 x 7 ) / 98
GCD(98, 7) = 686 / 98
GCD(98, 7) = 7
Step2:
Here we consider the GCD from the above i.e. 7 as first number and the next as 84
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(7, 84) = 84
GCD(7, 84) = ( 7 x 84 ) / 84
GCD(7, 84) = 588 / 84
GCD(7, 84) = 7
Step3:
Here we consider the GCD from the above i.e. 7 as first number and the next as 85
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(7, 85) = 595
GCD(7, 85) = ( 7 x 85 ) / 595
GCD(7, 85) = 595 / 595
GCD(7, 85) = 1
GCD of 98, 7, 84, 85 is 1
