Make use of GCD Calculator to determine the Greatest Common Divisor of 211, 130, 79, 661 i.e. 1 largest integer that divides all the numbers equally.
GCD of 211, 130, 79, 661 is 1
GCD(211, 130, 79, 661) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 211, 130, 79, 661 is 1
GCD(211, 130, 79, 661) = 1
Given Input numbers are 211, 130, 79, 661
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 211

1, 2, 5, 10, 13, 26, 65, 130
Divisors of 79
List of positive integer divisors of 79 that divides 79 without a remainder.
1, 79
Divisors of 661
List of positive integer divisors of 661 that divides 661 without a remainder.
1, 661
Greatest Common Divisior
We found the divisors of 211, 130, 79, 661 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 211, 130, 79, 661 is 1.
Therefore, GCD of numbers 211, 130, 79, 661 is 1
Given Input Data is 211, 130, 79, 661
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 211 is 211
Prime Factorization of 130 is 2 x 5 x 13
Prime Factorization of 79 is 79
Prime Factorization of 661 is 661
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(211, 130) = 27430
GCD(211, 130) = ( 211 x 130 ) / 27430
GCD(211, 130) = 27430 / 27430
GCD(211, 130) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 79
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 79) = 79
GCD(1, 79) = ( 1 x 79 ) / 79
GCD(1, 79) = 79 / 79
GCD(1, 79) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 661
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 661) = 661
GCD(1, 661) = ( 1 x 661 ) / 661
GCD(1, 661) = 661 / 661
GCD(1, 661) = 1
GCD of 211, 130, 79, 661 is 1
