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 (1125, 1350).
Properties of GCF
- The GCF of two or more given numbers is always less than the given numbers. Eg- GCF of 1125 and 1350 is 225, where 225 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, 125, 225, 375, 1125 are exact divisors of 1125 and 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 27, 30, 45, 50, 54, 75, 90, 135, 150, 225, 270, 450, 675, 1350 are exact divisors of 1350.
- Every number other than 1 has at least two factors, namely the number itself and 1.
- Each number is a factor of itself. Eg. 1125 and 1350 are factors of themselves respectively.
- 1 is a factor of every number. Eg. 1 is a factor of 1125 and also of 1350.
Steps to find Factors of 1125 and 1350
- Step 1. Find all the numbers that would divide 1125 and 1350 without leaving any remainder. Starting with the number 1 upto 562 (half of 1125) and 1 upto 675 (half of 1350). The number 1 and the number itself are always factors of the given number.

Hence, Factors of
1125 are 1, 3, 5, 9, 15, 25, 45, 75, 125, 225, 375, and 1125
And, Factors of
1350 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 27, 30, 45, 50, 54, 75, 90, 135, 150, 225, 270, 450, 675, and 1350
Examples of GCF
Sammy baked 1125 chocolate cookies and 1350 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 1125 and 1350.
GCF of 1125 and 1350 is 225.
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(1125, 1350) = ( 1125 * 1350 ) / LCM(1125, 1350) = 225.
What is the GCF of 1125 and 1350?GCF of 1125 and 1350 is 225.
Ram has 1125 cans of Pepsi and 1350 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 1125 and 1350. Hence GCF of 1125 and 1350 is 225. So the number of tables that can be arranged is 225.
Rubel is creating individual servings of starters for her birthday party. He has 1125 pizzas and 1350 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 1125 and 1350. Thus GCF of 1125 and 1350 is 225.
