No.
The GCF is 17.
When doing fractions it is the greatest common factor (GCF) and the least common multiple (LCM). You want the GCF when you are reducing fractions to their simplest form. When changing the denominators to a common one, you want the LCM.
3 and any multiple of 3. Multiples of 3 that differ by 3.
The Greatest Common Factor (GCF) is: 8
The greatest common factor is 2
18 and 27
The least common multiple is 30. The greatest common factor is 3.
The GCF is 17.
They're infinite. You're probably looking for the greatest common factor or least common multiple.
No, 4 is the greatest common factor of those numbers. Multiples are larger.
because there are infinite multiples of a number. ex:2,4,6,8,10,12,14,16,18,20...etc
The Greatest Common Factor (GCF) is: 41The Least Common Multiple (LCM) is: 246
Common Multiples are multiples which are common to both numbers So Multiples of 9 are 9, 18, 27, 36 etc... Multiples of 27 are 27, 54, 81 etc... you can work out the least common multiple as 27 We can see that 9 is a factor of 27 so all multiples of 27 are a common multiple with 9. But as there is no upper limit we can not work out a greatest common multiple as they bigger they get the closer they get to infinity! You tend to work out Greatest Common Factor and Least Common Multiple with regards numbers.
No.
479 is a prime number. Numbers having a greatest common factor of 479 are 479 and 958, or any other two or more multiples of 479.
When doing fractions it is the greatest common factor (GCF) and the least common multiple (LCM). You want the GCF when you are reducing fractions to their simplest form. When changing the denominators to a common one, you want the LCM.
When you are comparing 12 to a multiple of itself, or when you are comparing multiples of 12 that differ by 12.
