Make use of GCD Calculator to determine the Greatest Common Divisor of 530, 291, 20, 953 i.e. 1 largest integer that divides all the numbers equally.
GCD of 530, 291, 20, 953 is 1
GCD(530, 291, 20, 953) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 530, 291, 20, 953 is 1
GCD(530, 291, 20, 953) = 1
Given Input numbers are 530, 291, 20, 953
To find the GCD of numbers using factoring list out all the divisors of each number

1, 953
Greatest Common Divisior
We found the divisors of 530, 291, 20, 953 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 530, 291, 20, 953 is 1.
Therefore, GCD of numbers 530, 291, 20, 953 is 1
Given Input Data is 530, 291, 20, 953
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 530 is 2 x 5 x 53
Prime Factorization of 291 is 3 x 97
Prime Factorization of 20 is 2 x 2 x 5
Prime Factorization of 953 is 953
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(530, 291) = 154230
GCD(530, 291) = ( 530 x 291 ) / 154230
GCD(530, 291) = 154230 / 154230
GCD(530, 291) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 20
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 20) = 20
GCD(1, 20) = ( 1 x 20 ) / 20
GCD(1, 20) = 20 / 20
GCD(1, 20) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 953
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 953) = 953
GCD(1, 953) = ( 1 x 953 ) / 953
GCD(1, 953) = 953 / 953
GCD(1, 953) = 1
GCD of 530, 291, 20, 953 is 1
