What are the common factor of 21 and 30?
The factors of 21 are 1, 3, 7, and 21. The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. The common factors are 1 and 3. The greatest common factor is 3.
What is the greatest common factor of 21 and 30?
The GCF of 21 and 30 is 3Definition: 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 21 are 1, 3, 7, and 21.The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30.The common factors are 1 and 3. Therefore, the greatest common factor is 3.
What are the common factors of 21 30 and 44?
The GCF is 1.
What is the greatest common factor of 21 30 and 35?
One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 21 are 1, 3, 7, and 21. The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. The factors of 35 are 1, 5, 7, and 35. There is only one common factor: 1. Therefore, the greatest common factor is 1. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 21 are 3 and 7. The prime factors of 30 are 2, 3, and 5. The prime factors of 35 are 5 and 7. There are no prime factors in common, so the greatest common factor is 1.
What is the greatest common factor of 12 21 and 30?
The greatest common factor of 12 21 and 30 is 3The factors of 12 are: 1, 2, 3, 4, 6, 12The factors of 21 are: 1, 3, 7, 21The factors of 30 are: 1, 2, 3, 5, 6, 10, 15, 30The common factors are: 1, 3The Greatest Common Factor (GCF) is: 3
What is the greatest common factor of two different numbers?
All numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors. The largest of these is known as the greatest common factor, or GCF.Example: 30 and 42The factors of 30 are:1, 2, 3, 5, 6, 10, 15, 30The factors of 42 are:1, 2, 3, 6, 7, 14, 21, 42The common factors are:1, 2, 3, 6The Greatest Common Factor:GCF = 6
How do you find a common factor?
All numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors. One way to find them is to list all the factors of a set of numbers. Example 30 and 42 1, 2, 3, 5, 6, 10, 15, 30 1, 2, 3, 6, 7, 14, 21, 42 1, 2, 3 and 6 appear on both lists. They are the common factors of 30 and 42.
What is the greatest common factor of 12 30 and 44?
The first question you need to investigate: Is there ANYnumber that is a common factor of 21, 30, and 44 ?If we can't find at least two of them, then we don't have to worry about "greatest".The factors of 21 are: 1, 3, 7, and 21.The factors of 30 are: 1, 2, 3, 5, 6, 10, 15, and 30.The factors of 44 are: 1, 2, 4, 11, 22, and 44.The only factor common to 21, 30, and 44 is '1'.Technically, I guess the answer to the question is 'Yes'. There is one common factor, so it'salso the greatest.
How do you set up common factors?
Example: 30 and 42 The factors of 30 are: 1, 2, 3, 5, 6, 10, 15, 30 The factors of 42 are: 1, 2, 3, 6, 7, 14, 21, 42 The common factors are: 1, 2, 3, 6
