A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

Is the least common multiple of two numbers always divisible by the greatest common factor of the two numbers?

Yes, the least common multiple of two numbers is always divisible by those numbers' greatest common factor.


How do you know whether to use the greatest common factor or the least common multiple to solve a problem?

the least common multiple is what the numbers you are using divide into. e.g. 3 and 6 have 12 as the common factor. the greatest common factor is what divides into your numbers. 6 and 9 have 3 as the greatest common factor


What is the least common multiple of 5 and 23?

The least common multiple of two numbers is the product of the two numbers divided by their greatest common factor. The greatest common factor of 5 and 23 is 1. (See related question "What is the greatest common factor of 5 and 23?" for this calculation.) So, the least common multiple is 5 x 23 ÷ 1 = 115.


When a number is a multiple of another the GCF of the numbers is the greatest common factor?

The GCF of the numbers is the greatest common factor no matter what their relationship is. When one number is a multiple of another number, the GCF is the smaller number.


What is the greatest common multiple between 12 and 15?

There is no "greatest common multiple" for any pair of numbers. If you meant greatest common factor, the answer is 3.


When the greatest common factor is 1 is the least common multiple of these numbers always the product of the numbers?

Yes - if two numbers share no common factors (besides 1) the least common multiple will be the product of the numbers.


What is the least common multiple of 56 and 64?

The least common multiple is the product of the two numbers divided by their greatest common factor. Their greatest common factor is 8, so the least common multiple is 56 x 64 ÷ 8 = 448.


What is the greatest common multiple of 36 and 54?

The greatest common multiple of any set of integers is infinite.


How are greatest common factor and least common multiple different?

The greatest common factor, or GCF, is the largest number that can go into a set of given numbers evenly. The least common multiple, or LCM, is the smallest number that a given set of numbers can go into evenly.


What is the greatest common multiple of 32and 55?

The greatest common multiple of any set of positive numbers is infinity.I suspect you actually want to know the greatest common factor and not multiple.The greatest common factor is 1.


What is the least common multiple of 15 and 32?

The least common multiple of two numbers is the product of the two numbers divided by their greatest common factor. The greatest common factor of 15 and 32 is 1, so the least common multiple is 15 x 32 ÷ 1 = 480.


What is the least common multiple of 7 and 159?

The least common multiple of two numbers is the product of the two numbers divided by their greatest common factor. The greatest common factor of 7 and 159 is 1, so the least common multiple is 7 x 159 ÷ 1 = 1113.


What is the least common multiple of 28 and 48?

The least common multiple of two numbers is the product of the two numbers divided by their greatest common factor. The greatest common factor of 28 and 48 is 4. Therefore, the least common multiple is 28 x 48 ÷ 4 = 336.


What is the least common multiple of 2 and 211?

The least common multiple of two numbers is the product of the two numbers divided by their greatest common factor. The greatest common factor of 2 and 211 is 1. (See related question "What is the greatest common factor of 2 and 211?" in the link below for more information on this calculation.) So, the least common multiple is 2 x 211 ÷ 1 = 422.


What two numbers have a greatest common factor of 8 and least common multiple of 48?

8 and 48


What is the greatest common factor and least common multiple of 24?

It is not possible to give a sensible answer to this question. The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers. The least common multiple (LCM) refers to a multiple that is COMMON to two or more numbers. You have only one number in the question!


What is the greatest common multiple of 66 and 143?

The greatest common multiple is an infinite number and not very practical for everyday use. The greatest common factor of those two numbers is 11.


What is the least common multiple of 2 coprime numbers?

The least common multiple of two numbers is the product of those two numbers divided by their greatest common factor. It the two numbers are coprime (or relatively prime), their greatest common factor is 1. Therefore, their least common multiple is a x b ÷ GCF (of a and b) = a x b ÷ 1 = a x b. The least common multiple of two coprime numbers is the numbers multiplied together.


What is the gcm of 14 and 39?

There is no such calculation as the greatest common multiple of two numbers, because numbers trail on infinitely. The least common multiple however is 546, while the greatest common factor is 1.


The least common multiple of 2 numbers is 72 the greatest common factor is 12 what is the numbers which is the answer?

12 and 72


What is the least common multiple of 14 and 70?

Since 70 is a multiple of 14, it is the least common multiple. Or, you can determine it as you would any pair of numbers. The least common multiple of two numbers is the product of the two numbers divided by their greatest common factor. The greatest common factor of 14 and 70 is 14. Therefore, the least common multiple 14 x 70 ÷ 14 = 70.


When a number is a multiple of another the greatest common factor of the numbers is the greater of the numbers?

No, the GCF is the lesser of the numbers.


What number and 8 have the greatest common factor of 8 and the least common multiple of 24?

Both numbers must be multiples of 8, since their greatest common factor is 8. The numbers cannot be larger than 24, since it is their least common multiple. One of the numbers is 8. The only other multiples of 8 that are equal to or less than 24 are 16 and 24. 8 and 16 have greatest common factor of 8 but least common multiple of 16, so it cannot be this pair. 8 and 24 have greatest common factor of 8 and least common multiple of 24, so this is the solution.


What is the greatest of the common factors of two or more numbers called?

The greatest common factor between two numbers. There is no term.


What is the least common multiple of 44 and 60?

The least common multiple is the product of the two numbers divided by their greatest common factor. The greatest common factor of 44 and 60 is 4, so the least common multiple is 44 x 60 ÷ 4 = 660.
