Make use of GCD Calculator to determine the Greatest Common Divisor of 10, 75, 20 i.e. 5 largest integer that divides all the numbers equally.
GCD of 10, 75, 20 is 5
GCD(10, 75, 20) = 5
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 10, 75, 20 is 5
GCD(10, 75, 20) = 5
Given Input numbers are 10, 75, 20
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 10
List of positive integer divisors of 10 that divides 10 without a remainder.
1, 2, 5, 10
Divisors of 75
List of positive integer divisors of 75 that divides 75 without a remainder.
1, 3, 5, 15, 25, 75
Divisors of 20
List of positive integer divisors of 20 that divides 20 without a remainder.
1, 2, 4, 5, 10, 20
Greatest Common Divisior
We found the divisors of 10, 75, 20 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 10, 75, 20 is 5.
Therefore, GCD of numbers 10, 75, 20 is 5
Given Input Data is 10, 75, 20
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 10 is 2 x 5
Prime Factorization of 75 is 3 x 5 x 5
Prime Factorization of 20 is 2 x 2 x 5
Highest common occurrences in the given inputs are 51
Multiplying them we get the GCD as 5
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(10, 75) = 150
GCD(10, 75) = ( 10 x 75 ) / 150
GCD(10, 75) = 750 / 150
GCD(10, 75) = 5
Step2:
Here we consider the GCD from the above i.e. 5 as first number and the next as 20
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(5, 20) = 20
GCD(5, 20) = ( 5 x 20 ) / 20
GCD(5, 20) = 100 / 20
GCD(5, 20) = 5
GCD of 10, 75, 20 is 5
