Definition of GCF

Greatest common factor commonly known as GCF of the two numbers is the highest possible number which completely divides given numbers, i.e. without leaving any remainder. It is represented as GCF (225, 275).

Properties of GCF

The GCF of two or more given numbers is always less than the given numbers. Eg- GCF of 225 and 275 is 25, where 25 is less than both the numbers.
If the given numbers are consecutive than GCF is always 1.
Product of two numbers is always equal to the product of their GCF and LCM.
The GCF of two given numbers where one of them is a prime number is either 1 or the number itself.

What are factors?

In mathematics, a factor is that number which divides into another number exactly, without leaving a remainder. A factor of a number can be positive or negative.

Properties of Factors

Every factor of a number is an exact divisor of that number, example 1, 3, 5, 9, 15, 25, 45, 75, 225 are exact divisors of 225 and 1, 5, 11, 25, 55, 275 are exact divisors of 275.
Every number other than 1 has at least two factors, namely the number itself and 1.
Each number is a factor of itself. Eg. 225 and 275 are factors of themselves respectively.
1 is a factor of every number. Eg. 1 is a factor of 225 and also of 275.

Steps to find Factors of 225 and 275

Step 1. Find all the numbers that would divide 225 and 275 without leaving any remainder. Starting with the number 1 upto 112 (half of 225) and 1 upto 137 (half of 275). The number 1 and the number itself are always factors of the given number.

225 ÷ 1 : Remainder = 0

275 ÷ 1 : Remainder = 0

225 ÷ 3 : Remainder = 0

275 ÷ 5 : Remainder = 0

225 ÷ 5 : Remainder = 0

275 ÷ 11 : Remainder = 0

225 ÷ 9 : Remainder = 0

275 ÷ 25 : Remainder = 0

225 ÷ 15 : Remainder = 0

275 ÷ 55 : Remainder = 0

225 ÷ 25 : Remainder = 0

275 ÷ 275 : Remainder = 0

225 ÷ 45 : Remainder = 0

225 ÷ 75 : Remainder = 0

225 ÷ 225 : Remainder = 0

Hence, Factors of 225 are 1, 3, 5, 9, 15, 25, 45, 75, and 225

And, Factors of 275 are 1, 5, 11, 25, 55, and 275

Examples of GCF

Sammy baked 225 chocolate cookies and 275 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 225 and 275.
GCF of 225 and 275 is 25.

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(225, 275) = ( 225 * 275 ) / LCM(225, 275) = 25.

What is the GCF of 225 and 275?

GCF of 225 and 275 is 25.

Ram has 225 cans of Pepsi and 275 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 225 and 275. Hence GCF of 225 and 275 is 25. So the number of tables that can be arranged is 25.

Rubel is creating individual servings of starters for her birthday party. He has 225 pizzas and 275 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 225 and 275. Thus GCF of 225 and 275 is 25.

Ariel is making ready to eat meals to share with friends. She has 225 bottles of water and 275 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 225 and 275. So the GCF of 225 and 275 is 25.
