What is the highest common factor of 5 and 15?
Since 5 is a factor of 15, it is automatically the GCF.
WHAT IS THE COMMON FACTOR OF 15 20 120?
The highest common factor is 5
What is the common factor of 15 and 40?
5
What is the common factor of 10 and 15?
The Common Factors of 10 and 15 are 1 and 5
What is the lowest common multiple of 18 and 15?
Prime factors: 18 = 2 x 3 x 3, 15 = 3 x 5 Ignore one of the common factor 3 and multiply others, ie 2 x 3 x 3 x 5 = 90 (5 x 18, 6 x 15)It is: 90
What is the Common factor of 18 and 15?
The factors of 15 are 1, 3, 5, and 15. The factors of 18 are 1, 2, 3, 6, 9, and 18. The common factors of 15 and 18 are 1 and 3.
What is the greatest common factor of 5 and 15?
5 is the greatest common factor of 5 and 15. The only other common factor is 1.Since 5 is a factor of 15, it is automatically the GCF.
Is 10 a common factor of 10 and15?
It can be. 10 is a common factor of 50 and 60.
What is the greatest common factor of 18 15 and 18?
The GCF of 15 and 18 is 3. The easiest way to find the answer is to notice that the difference between 15 and 18 is 3. The GCF of a pair of numbers can't be any greater than its difference. Since we can see that 3 is a factor of both 15 and 18, it is clearly the GCF.Another way to find the answer is to write the prime factorizations of each number in the set.The prime factorization of 15 is 3*5The prime factorization of 18 is 2*3*3So the GCF of 15 and 18 is 3.
Highest common factor of 60 and 75?
The GCF is 15.
How do you get the greatest common factor of 5 and 15?
Since 5 is a factor of 15, it is automatically the greatest common factor of the pair.
What are the pairs of numbers between 8 and 18 that have 5 as their greatest common factor?
10 and 15
Find the pairs between 8 and 18 that have 5 as their greatest common factor?
10 and 15
What is the GCF of 15 and 18 and how do you show the work?
Factor them. 3 x 5 = 15 2 x 3 x 3 = 18 Select the common factor(s). The GCF is 3.
What are the common factors of 5 and 18?
Since 5 is prime, and not a factor of 18, the only positive integer common factor of 5 and 18 is 1.
What are the common factor of 15 and 18?
The common factors of 15 and 18 are 1 and 3Common factors of 15 and 18 are: 1 and 3.
What are the common factors and greatest common factor of 15?
There is neither a greatest common factor nor common factors of a single number, such as 15, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor. The factors of 15 are 1, 3, 5, and 15. The prime factors of 15 are 3 and 5. Examples: The common factors of 6 and 15 are 1 and 3; the greatest common factor is 3. The common factors of 15 and 18 are 1 and 3; the greatest common factor is 3. The common factors of 15 and 55 are 1 and 5; the greatest common factor is 5.
