Make use of GCD Calculator to determine the Greatest Common Divisor of 19, 13, 64, 30 i.e. 1 largest integer that divides all the numbers equally.
GCD of 19, 13, 64, 30 is 1
GCD(19, 13, 64, 30) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 19, 13, 64, 30 is 1
GCD(19, 13, 64, 30) = 1
Given Input numbers are 19, 13, 64, 30
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 19
List of positive integer divisors of 19 that divides 19 without a remainder.
1, 19
Divisors of 13
List of positive integer divisors of 13 that divides 13 without a remainder.
1, 13
Divisors of 64
List of positive integer divisors of 64 that divides 64 without a remainder.
1, 2, 4, 8, 16, 32, 64
Divisors of 30
List of positive integer divisors of 30 that divides 30 without a remainder.
1, 2, 3, 5, 6, 10, 15, 30
Greatest Common Divisior
We found the divisors of 19, 13, 64, 30 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 19, 13, 64, 30 is 1.
Therefore, GCD of numbers 19, 13, 64, 30 is 1
Given Input Data is 19, 13, 64, 30
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 19 is 19
Prime Factorization of 13 is 13
Prime Factorization of 64 is 2 x 2 x 2 x 2 x 2 x 2
Prime Factorization of 30 is 2 x 3 x 5
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(19, 13) = 247
GCD(19, 13) = ( 19 x 13 ) / 247
GCD(19, 13) = 247 / 247
GCD(19, 13) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 64
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 64) = 64
GCD(1, 64) = ( 1 x 64 ) / 64
GCD(1, 64) = 64 / 64
GCD(1, 64) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 30
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 30) = 30
GCD(1, 30) = ( 1 x 30 ) / 30
GCD(1, 30) = 30 / 30
GCD(1, 30) = 1
GCD of 19, 13, 64, 30 is 1
