Make use of GCD Calculator to determine the Greatest Common Divisor of 69, 5, 15, 90 i.e. 1 largest integer that divides all the numbers equally.
GCD of 69, 5, 15, 90 is 1
GCD(69, 5, 15, 90) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 69, 5, 15, 90 is 1
GCD(69, 5, 15, 90) = 1
Given Input numbers are 69, 5, 15, 90
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 69
List of positive integer divisors of 69 that divides 69 without a remainder.
1, 3, 23, 69
Divisors of 5

1, 5
Divisors of 15
List of positive integer divisors of 15 that divides 15 without a remainder.
1, 3, 5, 15
Divisors of 90
List of positive integer divisors of 90 that divides 90 without a remainder.
1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90
Greatest Common Divisior
We found the divisors of 69, 5, 15, 90 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 69, 5, 15, 90 is 1.
Therefore, GCD of numbers 69, 5, 15, 90 is 1
Given Input Data is 69, 5, 15, 90
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 69 is 3 x 23
Prime Factorization of 5 is 5
Prime Factorization of 15 is 3 x 5
Prime Factorization of 90 is 2 x 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(69, 5) = 345
GCD(69, 5) = ( 69 x 5 ) / 345
GCD(69, 5) = 345 / 345
GCD(69, 5) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 15
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 15) = 15
GCD(1, 15) = ( 1 x 15 ) / 15
GCD(1, 15) = 15 / 15
GCD(1, 15) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 90
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 90) = 90
GCD(1, 90) = ( 1 x 90 ) / 90
GCD(1, 90) = 90 / 90
GCD(1, 90) = 1
GCD of 69, 5, 15, 90 is 1
