Make use of GCD Calculator to determine the Greatest Common Divisor of 25, 30, 47, 45 i.e. 1 largest integer that divides all the numbers equally.
GCD of 25, 30, 47, 45 is 1
GCD(25, 30, 47, 45) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 25, 30, 47, 45 is 1
GCD(25, 30, 47, 45) = 1
Given Input numbers are 25, 30, 47, 45
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 25
List of positive integer divisors of 25 that divides 25 without a remainder.
1, 5, 25
Divisors of 30
List of positive integer divisors of 30 that divides 30 without a remainder.
1, 2, 3, 5, 6, 10, 15, 30
Divisors of 47
List of positive integer divisors of 47 that divides 47 without a remainder.
1, 47
Divisors of 45
List of positive integer divisors of 45 that divides 45 without a remainder.
1, 3, 5, 9, 15, 45
Greatest Common Divisior
We found the divisors of 25, 30, 47, 45 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 25, 30, 47, 45 is 1.
Therefore, GCD of numbers 25, 30, 47, 45 is 1
Given Input Data is 25, 30, 47, 45
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 25 is 5 x 5
Prime Factorization of 30 is 2 x 3 x 5
Prime Factorization of 47 is 47
Prime Factorization of 45 is 3 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(25, 30) = 150
GCD(25, 30) = ( 25 x 30 ) / 150
GCD(25, 30) = 750 / 150
GCD(25, 30) = 5
Step2:
Here we consider the GCD from the above i.e. 5 as first number and the next as 47
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(5, 47) = 235
GCD(5, 47) = ( 5 x 47 ) / 235
GCD(5, 47) = 235 / 235
GCD(5, 47) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 45
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 45) = 45
GCD(1, 45) = ( 1 x 45 ) / 45
GCD(1, 45) = 45 / 45
GCD(1, 45) = 1
GCD of 25, 30, 47, 45 is 1
