Make use of GCD Calculator to determine the Greatest Common Divisor of 530, 129, 71, 802 i.e. 1 largest integer that divides all the numbers equally.
GCD of 530, 129, 71, 802 is 1
GCD(530, 129, 71, 802) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 530, 129, 71, 802 is 1
GCD(530, 129, 71, 802) = 1
Given Input numbers are 530, 129, 71, 802
To find the GCD of numbers using factoring list out all the divisors of each number

1, 2, 401, 802
Greatest Common Divisior
We found the divisors of 530, 129, 71, 802 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 530, 129, 71, 802 is 1.
Therefore, GCD of numbers 530, 129, 71, 802 is 1
Given Input Data is 530, 129, 71, 802
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 129 is 3 x 43
Prime Factorization of 71 is 71
Prime Factorization of 802 is 2 x 401
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, 129) = 68370
GCD(530, 129) = ( 530 x 129 ) / 68370
GCD(530, 129) = 68370 / 68370
GCD(530, 129) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 71
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 71) = 71
GCD(1, 71) = ( 1 x 71 ) / 71
GCD(1, 71) = 71 / 71
GCD(1, 71) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 802
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 802) = 802
GCD(1, 802) = ( 1 x 802 ) / 802
GCD(1, 802) = 802 / 802
GCD(1, 802) = 1
GCD of 530, 129, 71, 802 is 1
