Make use of GCD Calculator to determine the Greatest Common Divisor of 22, 15, 91 i.e. 1 largest integer that divides all the numbers equally.
GCD of 22, 15, 91 is 1
GCD(22, 15, 91) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 22, 15, 91 is 1
GCD(22, 15, 91) = 1
Given Input numbers are 22, 15, 91
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 22
List of positive integer divisors of 22 that divides 22 without a remainder.
1, 2, 11, 22
Divisors of 15
List of positive integer divisors of 15 that divides 15 without a remainder.
1, 3, 5, 15
Divisors of 91
List of positive integer divisors of 91 that divides 91 without a remainder.
1, 7, 13, 91
Greatest Common Divisior
We found the divisors of 22, 15, 91 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 22, 15, 91 is 1.
Therefore, GCD of numbers 22, 15, 91 is 1
Given Input Data is 22, 15, 91
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 22 is 2 x 11
Prime Factorization of 15 is 3 x 5
Prime Factorization of 91 is 7 x 13
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(22, 15) = 330
GCD(22, 15) = ( 22 x 15 ) / 330
GCD(22, 15) = 330 / 330
GCD(22, 15) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 91
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 91) = 91
GCD(1, 91) = ( 1 x 91 ) / 91
GCD(1, 91) = 91 / 91
GCD(1, 91) = 1
GCD of 22, 15, 91 is 1
