# What Is The GCF Of 3 15 And 9?

## How do you find the GCF on a calculator?

Greatest Common Factor and Greatest Common Divisor The TI-84 Plus CE will find the GCF/GCD of two numbers.

Example 1: To find the GCF of 24 and 30, press math, arrow over to NUM, and select 9:gcd( —either by moving the cursor down to option 9 and pressing enter, or by simply pressing 9)..

## What’s the GCF of 3 and 2?

Multiply the circled numbers together. This is the greatest common factor! In the example, gcf(18,36,90)=2⋅3⋅3=18 gcf ( 18 , 36 , 90 ) = 2 ⋅ 3 ⋅ 3 = 18 .

## What is the GCF of 3 and 18?

We found the factors and prime factorization of 3 and 18. The biggest common factor number is the GCF number. So the greatest common factor 3 and 18 is 3.

## What is the HCF of 9 15 and 24?

The GCF is the highest number that is a factor of all three of our “test subject numbers”. Ok, now let’s find what is common. There are 2s in 24 but not in 9 or 15, so there are no 2s in our GCF. There is one 3 in 24 and in 15 and two in 9 – so one 3 is common to all three numbers.
