Make use of GCD Calculator to determine the Greatest Common Divisor of 3, 15, 55 i.e. 1 largest integer that divides all the numbers equally.
GCD of 3, 15, 55 is 1
GCD(3, 15, 55) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 3, 15, 55 is 1
GCD(3, 15, 55) = 1
Given Input numbers are 3, 15, 55
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 3
List of positive integer divisors of 3 that divides 3 without a remainder.
1, 3
Divisors of 15
List of positive integer divisors of 15 that divides 15 without a remainder.
1, 3, 5, 15
Divisors of 55
List of positive integer divisors of 55 that divides 55 without a remainder.
1, 5, 11, 55
Greatest Common Divisior
We found the divisors of 3, 15, 55 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 3, 15, 55 is 1.
Therefore, GCD of numbers 3, 15, 55 is 1
Given Input Data is 3, 15, 55
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 3 is 3
Prime Factorization of 15 is 3 x 5
Prime Factorization of 55 is 5 x 11
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(3, 15) = 15
GCD(3, 15) = ( 3 x 15 ) / 15
GCD(3, 15) = 45 / 15
GCD(3, 15) = 3
Step2:
Here we consider the GCD from the above i.e. 3 as first number and the next as 55
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 55) = 165
GCD(3, 55) = ( 3 x 55 ) / 165
GCD(3, 55) = 165 / 165
GCD(3, 55) = 1
GCD of 3, 15, 55 is 1
