What is the factor tree for 15?
15 3, 5
How do you figure out two thirds of 15?
It is: 2/3 times 15 which is the same as 2/3 of 15 = 10
What multiplies to 15?
1 times 15 3 times 5 -1 times -15 -3 times -5
How do you factor 2x2 plus 13x plus 15?
2x 2+13x+15 = (2x + )(x + ) since the only way to get 2 is 1 times 2. The missing numbers must be filled with with 1 and 15 or 3 and 5 in some order, so by trial and error we get. 2x 2+13x+15 = (2x + 3 )(x + 5 )
How do you get the number 15 using only 1 2 3 and 4?
(4 times 3) plus 2 plus 1
Is 4 a factor of 15?
no 4 is not a factor of 15 because 4 times 3 is 12 and 4 times 5 is 20
What is a correct prime factor tree for 15?
It is: 3 times 5 = 15
What is the highest common factor of 6 and 15?
'6' has the factors, 1,2,3& 6. '15' has the factors od 1,3,5 & 15. '3' is the ONLY common and highest factor to both numbers. . Hence '3' is the HCF.
What is the longest factor string of 15?
5 times 3
The number 3 ------ of 12 and also of 15?
3 is a factor of 12 & a factor of 15, so it's a common factor between 12 & 15. Also, as it's the only common factor between them, in addition to 1 of course, it's the highest common factor between 12 & 15.
What is the greatest common factor of 3 and 15 and 9?
The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers. You have only one number in the question! The greatest factor of any number is itself.
Which number is not a common factor 15 45 and 90?
A common factor refers to a factor that is COMMON to two or more numbers. You have only one number in the question! Any integer greater than 154590 is not a factor.

What is 15 over 5 in simplest form?
You could say "1/3" or "one third" or "1 over 3". Or even 0.3333333333333333... Umm.... Your soppossed to find the GCF when you are simplifying... If the factors of 5 are only 1 and 5.. then that means the only factor 5 and 15 share is 1... so the answer is, IT'S ALREADY IN SIMPLEST FORM! But this answer is accurate. Because they only share a factor of 1.... you would put 1 as the numerator and 5 goes into 15 3 times so 3 is the denominator. But that still isn't correct. If they only share a factor of 1... Your answer is already in simplest form. :)
Greatest common factor of 15 and 35?
15 = 5*3 35 = 5*7 GCF: 5 (and the only comon factor)
What is the greatest common factor of 6 15 and 21?
The greatest common factor of 6, 15 and 21 is 3. The prime factorization of 6 is 2*3 The prime factorization of 15 is 3*5 The prime factorization of 21 is 3*7 The GCF is then 3, as it is the only common factor.
What is the greatest common factor of 6 and 15?
The greatest common factor (gcf) of 15 and 6 is 3.Factors of 6:1,2,3,6Factors of 15: 1,3,5,15The greatest common factor of the numbers 6 and 15 is 3.The GCF of 6 and 15 is 3. This gives you 2 and 5 respectively. You cannot get any more common factors that impact the end figure.The GCF is 3.Greatest common factor of 6 and 15 is 3.
