The factors of 45 are: 1, 3, 5, 9, 15, 45The factors of 81 are: 1, 3, 9, 27, 81The common factors are: 1, 3, 9The Greatest Common Factor (GCF) is: 9
What are the greatest common factors of 9 and 25?
Answer:The only common factor of 9 and 25 is 1.The greatest common factor of 9 and 25 is 1.Because 1 is the only common factor, the numbers are relatively prime.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 9 are 1, 3, and 9.The factors of 25 are 1, 5, and 25.The only common factor is 1. Therefore, the greatest common factor is 1, which means the numbers are relatively prime.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 9 are 3 and 3.The prime factors of 25 are 5 and 5.There are no prime factors in common, so the numbers are relatively prime, which means the greatest common factor is 1.
What is the greatest common factor of 45 and 5?
The GCF of 5 and 45 is 5Definition: 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 5 are 1 and 5.The factors of 45 are 1, 3, 5, 9, 15, and 45.The common factors are 1 and 5. Therefore, the greatest common factor is 5.The GCF/HCF of 5 and 45 is 5.
What is the greatest common factor of 45 and 100?
The GCF of 45 and 95 is 5. The factors of 45 are: 1, 3, 5, 9, 15, 45. The factors of 95 are: 1, 5, 19, 95. The common factors are: 1, 5. The Greatest Common Factor (GCF) is: 5
What are the greatest common factors of 18 and 45?

What is the greatest common factor of 9 and 5?
The greatest common factor of 5 and 9 is 1.
What are the common factors of 27 and 45?
The common factors of 27 and 45 are 1, 3, and 9. The greatest common factor of 27 and 45 is 9. 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 27 are 1, 3, 9, and 27. The factors of 45 are 1, 3, 5, 9, 15, and 45. The common factors are 1,3, and 9. Therefore, the greatest common factor is 9. 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 27 are 3, 3, and 3. The prime factors of 45 are 3, 3, and 5. The prime factors in common are 3 and 3, so the greatest common factor is 3 x 3 = 9.
What is the greatest common factor of 45 and 250?
Since the numbers end in either 5 or 0, you know that they are both divisible by, which means the greatest common factor is a multiple of 5. If you divide both numbers by 5, you get 45 ÷ 5 = 9 and 250 ÷ 5 = 50. The results, 9 and 50, do not have any factors in common, since the only factors of 9 besides 1 are multiples of 3, and 50 is not divisible by 3. Therefore, the greatest common factor must be 5. Another way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 45 are 1, 3, 5, 9, 15, and 45. The factors of 250 are 1, 2, 5, 10, 25, 50, 125, and 250. The common factors are 1 and 5. Therefore, the greatest common factor is 5. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 45 are 3, 3, and 5. The prime factors of 250 are 2, 5, 5, and 5. The prime factors in common are a single 5, so the greatest common factor is 5.

What are the common factors and greatest common factor of 9?
There is neither a greatest common factor nor common factors of a single number, such as 9, 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 9 are 1, 3, and 9. The prime factors of 9 are 3 and 3. Examples: The common factors of 9 and 24 are 1 and 3; the greatest common factor is 3. The common factors of 9 and 64 are only 1; the greatest common factor is 1. The common factors of 9 and 108 are 1, 3, and 9; the greatest common factor is 9.
