What are the common factors and greatest common factor of 4?

There is neither a greatest common factor nor common factors of a single number, such as 4, 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 4 are 1, 2, and 4. The prime factors of 4 are 2 and 2. Examples: The common factors of 4 and 36 are 1, 2, and 4; the greatest common factor is 4. The common factors of 4 and 54 are 1 and 2; the greatest common factor is 2.


What are the common factor of 32?

Short answer: There are no "common factors" of 32.There is neither a greatest common factor nor common factors of a single number, such as ??, 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.Examples:The common factors of 32 and 36 are 1, 2, and 4; the greatest common factor is 4.The common factors of 32 and 48 are 1, 2, 4, 8, and 16; the greatest common factor is 16.The common factors of 32 and 56 are 1, 2, 4, and 8; the greatest common factor is 8.The common factors of 32 and 63 are only 1; the greatest common factor is 1.The common factors of 32 and 90 are 1 and 2; the greatest common factor is 2.The common factors of 32 and 96 are 1, 2, 4, 8, 16, and 32; the greatest common factor is 32.The factors of 32 are 1,2,4,8,16 and 32.The factors of 32 are 1, 2, 4, 8, 16, 32. For them to be common, they have to be compared to another set of factors.


What are the greatest common factors of 4 8 and 16?

The common factors are: 1, 2, 4 The Greatest Common Factor (GCF) is: 4


What is the greatest common factor of 52 and 100?

The greatest common factor of 52 and 100 is 4. A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that both numbers have in common. 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 52 are 1, 2, 4, 13, 26, and 52. The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100. The common factors are 1, 2, and 4. Therefore, the greatest common factor is 4. It is: 4


What is the greatest common factor of 4 and 7?

The word "greatest" is a superlative. What that means is that there can only be one gcf. So there are not greatest common factors of 4 and 7, there is a GCF, which is 28.


What is the greatest common factor of 16 44?

A single number cannot have a greatest common factor because "common" refers to factors that two or more numbers have in common. You have only one number.


What is the greatest common factor of 36 and 64?

The GCF of 36 and 64 is 4Definition: A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Method: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 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36.The factors of 64 are 1, 2, 4, 8, 16, 32, and 64.The common factors are 1, 2, and 4. Therefore, the greatest common factor is 4.The GCF is 4.


What are the greatest common factors of 100 and 24?

the greatest common factor is 4. 2 and 4 are the only common factors of 100 and 24.


What are the common factors of 4 and 18?

Answer:The common factors of 4 and 18 are 1 and 2.The greatest common factor of 4 and 18 is 2.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 4 are 1, 2, and 4.The factors of 18 are 1, 2, 3, 6, 9, and 18.The common factors are 1 and 2; the greatest common factor is 2.The common factors and greatest common factor can also be calculated by identifying the common prime factors and multiplying them together to identify the greatest common factor, and then taking all the factors of it to determine the common factors.The prime factors of 4 are 2 and 2.The prime factors of 18 are 2, 3, and 3.The prime factors in common are a single 2, so the greatest common factor is 2. The factors of 2 are 1 and 2, which are the common factors.1 and 2

1, 2, 4 are the common factors of 12 and 40, and 4 is the greatest common factor


What is the greatest common factor of 28 and 40?

Answer: 4Definition: A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Method: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 28 are 1, 2, 4, 7, 14, and 28.The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40.The common factors are 1, 2, and 4. Therefore, the greatest common factor is 4.The greatest common factor of the numbers 28 and 40 is 4.


What is the relationship between common factors and greatest common factors?

Common factors are factors that are shared by a given set of numbers, usually positive integers. Greatest common factors (sometimes abbreviated to GCFs) are the factors in these given sets that have the greatest value out of all common factors. Example: Factors of 9: 1, 3, 9 Factors of 15: 1, 3, 5, 15 The common factors of 9 and 15: 1, 3 The GCF: 3
