Greatest Common Divisior
We found the divisors of 247, 847, 782 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 247, 847, 782 is 1.
Therefore, GCD of numbers 247, 847, 782 is 1
Given Input Data is 247, 847, 782
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 247 is 13 x 19
Prime Factorization of 847 is 7 x 11 x 11
Prime Factorization of 782 is 2 x 17 x 23
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, 847) = 209209
GCD(247, 847) = ( 247 x 847 ) / 209209
GCD(247, 847) = 209209 / 209209
GCD(247, 847) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 782
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 782) = 782
GCD(1, 782) = ( 1 x 782 ) / 782
GCD(1, 782) = 782 / 782
GCD(1, 782) = 1
GCD of 247, 847, 782 is 1
