Make use of GCD Calculator to determine the Greatest Common Divisor of 402, 163, 80, 479 i.e. 1 largest integer that divides all the numbers equally.
GCD of 402, 163, 80, 479 is 1
GCD(402, 163, 80, 479) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 402, 163, 80, 479 is 1
GCD(402, 163, 80, 479) = 1
Given Input numbers are 402, 163, 80, 479
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 402

1, 2, 4, 5, 8, 10, 16, 20, 40, 80
Divisors of 479
List of positive integer divisors of 479 that divides 479 without a remainder.
1, 479
Greatest Common Divisior
We found the divisors of 402, 163, 80, 479 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 402, 163, 80, 479 is 1.
Therefore, GCD of numbers 402, 163, 80, 479 is 1
Given Input Data is 402, 163, 80, 479
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 402 is 2 x 3 x 67
Prime Factorization of 163 is 163
Prime Factorization of 80 is 2 x 2 x 2 x 2 x 5
Prime Factorization of 479 is 479
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(402, 163) = 65526
GCD(402, 163) = ( 402 x 163 ) / 65526
GCD(402, 163) = 65526 / 65526
GCD(402, 163) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 80
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 80) = 80
GCD(1, 80) = ( 1 x 80 ) / 80
GCD(1, 80) = 80 / 80
GCD(1, 80) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 479
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 479) = 479
GCD(1, 479) = ( 1 x 479 ) / 479
GCD(1, 479) = 479 / 479
GCD(1, 479) = 1
GCD of 402, 163, 80, 479 is 1
