Make use of GCD Calculator to determine the Greatest Common Divisor of 221, 947, 131, 151 i.e. 1 largest integer that divides all the numbers equally.
GCD of 221, 947, 131, 151 is 1
GCD(221, 947, 131, 151) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 221, 947, 131, 151 is 1
GCD(221, 947, 131, 151) = 1
Given Input numbers are 221, 947, 131, 151
To find the GCD of numbers using factoring list out all the divisors of each number

Greatest Common Divisior
We found the divisors of 221, 947, 131, 151 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 221, 947, 131, 151 is 1.
Therefore, GCD of numbers 221, 947, 131, 151 is 1
Given Input Data is 221, 947, 131, 151
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 221 is 13 x 17
Prime Factorization of 947 is 947
Prime Factorization of 131 is 131
Prime Factorization of 151 is 151
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(221, 947) = 209287
GCD(221, 947) = ( 221 x 947 ) / 209287
GCD(221, 947) = 209287 / 209287
GCD(221, 947) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 131
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 131) = 131
GCD(1, 131) = ( 1 x 131 ) / 131
GCD(1, 131) = 131 / 131
GCD(1, 131) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 151
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 151) = 151
GCD(1, 151) = ( 1 x 151 ) / 151
GCD(1, 151) = 151 / 151
GCD(1, 151) = 1
GCD of 221, 947, 131, 151 is 1
