• Factors for 18: 1, 2, 3, 6, 9, 18
• Factors for 270: 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270

Hence, GCf of 18 and 270 is 18

#### What does GCF mean in mathematics?

Greatest Common Fcator (GCF) or also sometimes written as greates common divisor is the largest number that can evenly divide the given two numbers. GCF is represented as GCF (18, 270).

#### Properties of GCF

• Given two numbers 18 and 270, such that GCF is 18 where 18 will always be less than 18 and 270.
• GCF of two numbers is always equal to 1 in case given numbers are consecutive.
• The product of GCF and LCM of two given numbers is equal to the product of two numbers.
• The GCF of two given numbers is either 1 or the number itself if one of them is a prime number.

#### What is the definition of factors?

In mathematics, factors are number, algebraic expressions which when multiplied together produce desired product. A factor of a number can be positive or negative.

#### Properties of Factors

• Each number is a factor of itself. Eg. 18 and 270 are factors of themselves respectively.
• Every number other than 1 has at least two factors, namely the number itself and 1.
• Every factor of a number is an exact divisor of that number, example 1, 2, 3, 6, 9, 18 are exact divisors of 18 and 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270 are exact divisors of 270.
• 1 is a factor of every number. Eg. 1 is a factor of 18 and also of 270.
• Every number is a factor of zero (0), since 18 x 0 = 0 and 270 x 0 = 0.

#### Steps to find Factors of 18 and 270

• Step 1. Find all the numbers that would divide 18 and 270 without leaving any remainder. Starting with the number 1 upto 9 (half of 18) and 1 upto 135 (half of 270). The number 1 and the number itself are always factors of the given number.
18 ÷ 1 : Remainder = 0
270 ÷ 1 : Remainder = 0
18 ÷ 2 : Remainder = 0
270 ÷ 2 : Remainder = 0
18 ÷ 3 : Remainder = 0
270 ÷ 3 : Remainder = 0
18 ÷ 6 : Remainder = 0
270 ÷ 5 : Remainder = 0
18 ÷ 9 : Remainder = 0
270 ÷ 6 : Remainder = 0
18 ÷ 18 : Remainder = 0
270 ÷ 9 : Remainder = 0
270 ÷ 10 : Remainder = 0
270 ÷ 15 : Remainder = 0
270 ÷ 18 : Remainder = 0
270 ÷ 27 : Remainder = 0
270 ÷ 30 : Remainder = 0
270 ÷ 45 : Remainder = 0
270 ÷ 54 : Remainder = 0
270 ÷ 90 : Remainder = 0
270 ÷ 135 : Remainder = 0
270 ÷ 270 : Remainder = 0

Hence, Factors of 18 are 1, 2, 3, 6, 9, and 18

And, Factors of 270 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, and 270

#### Examples of GCF

Sammy baked 18 chocolate cookies and 270 fruit and nut cookies to package in plastic containers for her friends at college. She wants to divide the cookies into identical boxes so that each box has the same number of each kind of cookies. She wishes that each box should have greatest number of cookies possible, how many plastic boxes does she need?

Since Sammy wants to pack greatest number of cookies possible. So for calculating total number of boxes required we need to calculate the GCF of 18 and 270.
GCF of 18 and 270 is 18.

What is the difference between GCF and LCM?

Major and simple difference betwen GCF and LCM is that GCF gives you the greatest common factor while LCM finds out the least common factor possible for the given numbers.

What is the relation between LCM and GCF (Greatest Common Factor)?

GCF and LCM of two numbers can be related as GCF(18, 270) = ( 18 * 270 ) / LCM(18, 270) = 18.

What is the GCF of 18 and 270?

GCF of 18 and 270 is 18.

Ram has 18 cans of Pepsi and 270 cans of Coca Cola. He wants to create identical refreshment tables that will be organized in his house warming party. He also doesn't want to have any can left over. What is the greatest number of tables that Ram can arrange?

To find the greatest number of tables that Ram can stock we need to find the GCF of 18 and 270. Hence GCF of 18 and 270 is 18. So the number of tables that can be arranged is 18.

Rubel is creating individual servings of starters for her birthday party. He has 18 pizzas and 270 hamburgers. He wants each serving to be identical, with no left overs. Can you help Rubel in arranging the same in greatest possible way?

The greatest number of servings Rubel can create would be equal to the GCF of 18 and 270. Thus GCF of 18 and 270 is 18.

Ariel is making ready to eat meals to share with friends. She has 18 bottles of water and 270 cans of food, which she would like to distribute equally, with no left overs. What is the greatest number of boxes Ariel can make?

The greatest number of boxes Ariel can make would be equal to GCF of 18 and 270. So the GCF of 18 and 270 is 18.
