Make use of GCD Calculator to determine the Greatest Common Divisor of 647, 813, 55, 271 i.e. 1 largest integer that divides all the numbers equally.
GCD of 647, 813, 55, 271 is 1
GCD(647, 813, 55, 271) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 647, 813, 55, 271 is 1
GCD(647, 813, 55, 271) = 1
Given Input numbers are 647, 813, 55, 271

Greatest Common Divisior
We found the divisors of 647, 813, 55, 271 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 647, 813, 55, 271 is 1.
Therefore, GCD of numbers 647, 813, 55, 271 is 1
Given Input Data is 647, 813, 55, 271
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 647 is 647
Prime Factorization of 813 is 3 x 271
Prime Factorization of 55 is 5 x 11
Prime Factorization of 271 is 271
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(647, 813) = 526011
GCD(647, 813) = ( 647 x 813 ) / 526011
GCD(647, 813) = 526011 / 526011
GCD(647, 813) = 1
Step2:
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
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 271
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 271) = 271
GCD(1, 271) = ( 1 x 271 ) / 271
GCD(1, 271) = 271 / 271
GCD(1, 271) = 1
GCD of 647, 813, 55, 271 is 1
