Make use of GCD Calculator to determine the Greatest Common Divisor of 400, 478, 38, 505 i.e. 1 largest integer that divides all the numbers equally.
GCD of 400, 478, 38, 505 is 1
GCD(400, 478, 38, 505) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 400, 478, 38, 505 is 1
GCD(400, 478, 38, 505) = 1
Given Input numbers are 400, 478, 38, 505
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 400
List of positive integer divisors of 400 that divides 400 without a remainder.
1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
Divisors of 478
List of positive integer divisors of 478 that divides 478 without a remainder.
1, 2, 239, 478
Divisors of 38
List of positive integer divisors of 38 that divides 38 without a remainder.
1, 2, 19, 38
Divisors of 505
List of positive integer divisors of 505 that divides 505 without a remainder.
1, 5, 101, 505
Greatest Common Divisior
We found the divisors of 400, 478, 38, 505 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 400, 478, 38, 505 is 1.
Therefore, GCD of numbers 400, 478, 38, 505 is 1
Given Input Data is 400, 478, 38, 505
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 400 is 2 x 2 x 2 x 2 x 5 x 5
Prime Factorization of 478 is 2 x 239
Prime Factorization of 38 is 2 x 19
Prime Factorization of 505 is 5 x 101
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(400, 478) = 95600
GCD(400, 478) = ( 400 x 478 ) / 95600
GCD(400, 478) = 191200 / 95600
GCD(400, 478) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 38
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 38) = 38
GCD(2, 38) = ( 2 x 38 ) / 38
GCD(2, 38) = 76 / 38
GCD(2, 38) = 2
Step3:
Here we consider the GCD from the above i.e. 2 as first number and the next as 505
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 505) = 1010
GCD(2, 505) = ( 2 x 505 ) / 1010
GCD(2, 505) = 1010 / 1010
GCD(2, 505) = 1
GCD of 400, 478, 38, 505 is 1
