Make use of GCD Calculator to determine the Greatest Common Divisor of 203, 639, 47, 160 i.e. 1 largest integer that divides all the numbers equally.
GCD of 203, 639, 47, 160 is 1
GCD(203, 639, 47, 160) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 203, 639, 47, 160 is 1
GCD(203, 639, 47, 160) = 1
Given Input numbers are 203, 639, 47, 160
To find the GCD of numbers using factoring list out all the divisors of each number

Greatest Common Divisior
We found the divisors of 203, 639, 47, 160 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 203, 639, 47, 160 is 1.
Therefore, GCD of numbers 203, 639, 47, 160 is 1
Given Input Data is 203, 639, 47, 160
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 203 is 7 x 29
Prime Factorization of 639 is 3 x 3 x 71
Prime Factorization of 47 is 47
Prime Factorization of 160 is 2 x 2 x 2 x 2 x 2 x 5
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(203, 639) = 129717
GCD(203, 639) = ( 203 x 639 ) / 129717
GCD(203, 639) = 129717 / 129717
GCD(203, 639) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 47
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 47) = 47
GCD(1, 47) = ( 1 x 47 ) / 47
GCD(1, 47) = 47 / 47
GCD(1, 47) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 160
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 160) = 160
GCD(1, 160) = ( 1 x 160 ) / 160
GCD(1, 160) = 160 / 160
GCD(1, 160) = 1
GCD of 203, 639, 47, 160 is 1
