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.
What is the greatest common factor of 15 and 75?
Since 15 is a factor of 75, and 15 is its own largest factor, the greatest common factor must be 15.Another way to determine the greatest common factor is to find all the factors of the numbers and compare them.The factors of 15 are 1, 3, 5, and 15.The factors of 75 are 1, 3, 5, 15, 25, and 75.The common factors are 1, 3, 5, and 15. Therefore, the greatest common factor is 15.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 15 are 3 and 5.The prime factors of 75 are 3, 5, and 5.The prime factors in common are 3 and 5, so the greatest common factor is 3 x 5 = 15.It is 15
What are the common factors and greatest common factors of 12 and 15?

What is the greatest common factor of 15 and 33?
Answer:The greatest common factor of 15 and 33 is 3.The common factors of 15 and 33 are 1 and 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 15 are 1, 3, 5, and 15.The factors of 33 are 1, 3, 11, and 33.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.The prime factors of 15 are 3 and 5.The prime factors of 33 are 3 and 11.The prime factors in common are 3, so the greatest common factor is 3.
