There is neither a greatest common factor nor common factors of a single number, such as 42, 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 42 are 1, 2, 3, 6, 7, 14, 21, and 42. Examples: The common factors of 25 and 42 are only 1; the greatest common factor is 1.

The common factors of 36 and 42 are 1, 2, 3, and 6; the greatest common factor is 6.

The common factors of 42 and 49 are 1 and 7; the greatest common factor is 7.

The common factors of 42 and 60 are 1, 2, 3, and 6; the greatest common factor is 6.

The common factors of 42 and 70 are 1, 2, 7, and 14; the greatest common factor is 14.

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

What is the greatest common factor of 42 and 86?

The GCF of 42 and 86 is 2. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. The factors of 86 are 1, 2, 43, and 86. The common factors are 1 and 2. Therefore, the greatest common factor is 2.


What are the common factors and greatest common factor of 21 and 42?

The common factors of 21 and 42 are 3, 7 and 21. The greatest common factor (GCF) is 21.


What is the greatest common factor of 42?

There is not a greatest common factor of 42 because there cannot be a greatest 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. The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. The prime factors of 42 are 2, 3, and 7. Examples: The greatest common factor of 36 and 42 is 6. The greatest common factor of 42 and 91 is 7. The greatest common factor of 42 and 375 is 3.


What is the greatest common factor of 35 and 42?

The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 35 are 5 and 7. The prime factors of 42 are 2, 3, and 7. The common prime factors are a single 7, so the greatest common factor is 7.


What is the greatest common factor of 39 and 42?

Answer:The common factors of 39 and 42 are 1 and 3.The greatest common factor of 39 and 42 is 3.Definition: A factor is a divisor - a number that will evenly divide into another number. The common factors of two or more numbers are all the factors that the numbers have in common. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Methods:One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them.The factors of 39 are 1, 3, 13, and 39.The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42.The common factors are 1 and 3. Therefore, the greatest common factor is 3.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. To then obtain the common factors, list all the factors of the greatest common factor.The prime factors of 39 are 3 and 13.The prime factors of 42 are 2, 3, and 7.The only prime factor in common is 3, so the greatest common factor is 3. The factors of 3 are 1 and 3, which are the common factors.
