Make use of GCD Calculator to determine the Greatest Common Divisor of 247, 791, 17, 203 i.e. 1 largest integer that divides all the numbers equally.
GCD of 247, 791, 17, 203 is 1
GCD(247, 791, 17, 203) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 247, 791, 17, 203 is 1
GCD(247, 791, 17, 203) = 1
Given Input numbers are 247, 791, 17, 203
To find the GCD of numbers using factoring list out all the divisors of each number

Greatest Common Divisior
We found the divisors of 247, 791, 17, 203 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 247, 791, 17, 203 is 1.
Therefore, GCD of numbers 247, 791, 17, 203 is 1
Given Input Data is 247, 791, 17, 203
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 247 is 13 x 19
Prime Factorization of 791 is 7 x 113
Prime Factorization of 17 is 17
Prime Factorization of 203 is 7 x 29
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, 791) = 195377
GCD(247, 791) = ( 247 x 791 ) / 195377
GCD(247, 791) = 195377 / 195377
GCD(247, 791) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 17
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 17) = 17
GCD(1, 17) = ( 1 x 17 ) / 17
GCD(1, 17) = 17 / 17
GCD(1, 17) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 203
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 203) = 203
GCD(1, 203) = ( 1 x 203 ) / 203
GCD(1, 203) = 203 / 203
GCD(1, 203) = 1
GCD of 247, 791, 17, 203 is 1
