Make use of GCD Calculator to determine the Greatest Common Divisor of 247, 187, 209 i.e. 1 largest integer that divides all the numbers equally.
GCD of 247, 187, 209 is 1
GCD(247, 187, 209) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 247, 187, 209 is 1
GCD(247, 187, 209) = 1
Given Input numbers are 247, 187, 209
To find the GCD of numbers using factoring list out all the divisors of each number

1, 11, 19, 209
Greatest Common Divisior
We found the divisors of 247, 187, 209 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 247, 187, 209 is 1.
Therefore, GCD of numbers 247, 187, 209 is 1
Given Input Data is 247, 187, 209
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 247 is 13 x 19
Prime Factorization of 187 is 11 x 17
Prime Factorization of 209 is 11 x 19
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(247, 187) = 46189
GCD(247, 187) = ( 247 x 187 ) / 46189
GCD(247, 187) = 46189 / 46189
GCD(247, 187) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 209
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 209) = 209
GCD(1, 209) = ( 1 x 209 ) / 209
GCD(1, 209) = 209 / 209
GCD(1, 209) = 1
GCD of 247, 187, 209 is 1
