Make use of GCD Calculator to determine the Greatest Common Divisor of 647, 247, 484, 643 i.e. 1 largest integer that divides all the numbers equally.
GCD of 647, 247, 484, 643 is 1
GCD(647, 247, 484, 643) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 647, 247, 484, 643 is 1
GCD(647, 247, 484, 643) = 1
Given Input numbers are 647, 247, 484, 643
To find the GCD of numbers using factoring list out all the divisors of each number

1, 643
Greatest Common Divisior
We found the divisors of 647, 247, 484, 643 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 647, 247, 484, 643 is 1.
Therefore, GCD of numbers 647, 247, 484, 643 is 1
Given Input Data is 647, 247, 484, 643
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 647 is 647
Prime Factorization of 247 is 13 x 19
Prime Factorization of 484 is 2 x 2 x 11 x 11
Prime Factorization of 643 is 643
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, 247) = 159809
GCD(647, 247) = ( 647 x 247 ) / 159809
GCD(647, 247) = 159809 / 159809
GCD(647, 247) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 484
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 484) = 484
GCD(1, 484) = ( 1 x 484 ) / 484
GCD(1, 484) = 484 / 484
GCD(1, 484) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 643
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 643) = 643
GCD(1, 643) = ( 1 x 643 ) / 643
GCD(1, 643) = 643 / 643
GCD(1, 643) = 1
GCD of 647, 247, 484, 643 is 1
