Make use of GCD Calculator to determine the Greatest Common Divisor of 405, 286, 15, 612 i.e. 1 largest integer that divides all the numbers equally.
GCD of 405, 286, 15, 612 is 1
GCD(405, 286, 15, 612) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 405, 286, 15, 612 is 1
GCD(405, 286, 15, 612) = 1
Given Input numbers are 405, 286, 15, 612
To find the GCD of numbers using factoring list out all the divisors of each number

1, 3, 5, 15
Divisors of 612
List of positive integer divisors of 612 that divides 612 without a remainder.
1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
Greatest Common Divisior
We found the divisors of 405, 286, 15, 612 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 405, 286, 15, 612 is 1.
Therefore, GCD of numbers 405, 286, 15, 612 is 1
Given Input Data is 405, 286, 15, 612
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 405 is 3 x 3 x 3 x 3 x 5
Prime Factorization of 286 is 2 x 11 x 13
Prime Factorization of 15 is 3 x 5
Prime Factorization of 612 is 2 x 2 x 3 x 3 x 17
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(405, 286) = 115830
GCD(405, 286) = ( 405 x 286 ) / 115830
GCD(405, 286) = 115830 / 115830
GCD(405, 286) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 15
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 15) = 15
GCD(1, 15) = ( 1 x 15 ) / 15
GCD(1, 15) = 15 / 15
GCD(1, 15) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 612
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 612) = 612
GCD(1, 612) = ( 1 x 612 ) / 612
GCD(1, 612) = 612 / 612
GCD(1, 612) = 1
GCD of 405, 286, 15, 612 is 1
