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 (1225, 10000).
Properties of GCF
- The GCF of two or more given numbers is always less than the given numbers. Eg- GCF of 1225 and 10000 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, 5, 7, 25, 35, 49, 175, 245, 1225 are exact divisors of 1225 and 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 125, 200, 250, 400, 500, 625, 1000, 1250, 2000, 2500, 5000, 10000 are exact divisors of 10000.
- Every number other than 1 has at least two factors, namely the number itself and 1.
- Each number is a factor of itself. Eg. 1225 and 10000 are factors of themselves respectively.
- 1 is a factor of every number. Eg. 1 is a factor of 1225 and also of 10000.
Steps to find Factors of 1225 and 10000
- Step 1. Find all the numbers that would divide 1225 and 10000 without leaving any remainder. Starting with the number 1 upto 612 (half of 1225) and 1 upto 5000 (half of 10000). The number 1 and the number itself are always factors of the given number.

10000 ÷ 250 : Remainder = 0
10000 ÷ 400 : Remainder = 0
10000 ÷ 500 : Remainder = 0
10000 ÷ 625 : Remainder = 0
10000 ÷ 1000 : Remainder = 0
10000 ÷ 1250 : Remainder = 0
10000 ÷ 2000 : Remainder = 0
10000 ÷ 2500 : Remainder = 0
10000 ÷ 5000 : Remainder = 0
10000 ÷ 10000 : Remainder = 0
Hence, Factors of
1225 are 1, 5, 7, 25, 35, 49, 175, 245, and 1225
And, Factors of

Examples of GCF
Sammy baked 1225 chocolate cookies and 10000 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 1225 and 10000.
GCF of 1225 and 10000 is 25.
A class has 1225 boys and 10000 girls. A choir teacher wants to form a choir team from this class such that the students are standing in equal rows also girls or boys will be in each row. Teacher wants to know the greatest number of students that could be in each row, can you help him?To find the greatest number of students that could be in each row, we need to find the GCF of 1225 and 10000. Hence, GCF of 1225 and 10000 is 25.
What is the relation between LCM and GCF (Greatest Common Factor)?GCF and LCM of two numbers can be related as GCF(1225, 10000) = ( 1225 * 10000 ) / LCM(1225, 10000) = 25.
What is the GCF of 1225 and 10000?GCF of 1225 and 10000 is 25.
Ram has 1225 cans of Pepsi and 10000 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 1225 and 10000. Hence GCF of 1225 and 10000 is 25. So the number of tables that can be arranged is 25.
Mary has 1225 blue buttons and 10000 white buttons. She wants to place them in identical groups without any buttons left, in the greatest way possible. Can you help Mary arranging them in groups?Greatest possible way in which Mary can arrange them in groups would be GCF of 1225 and 10000. Hence, the GCF of 1225 and 10000 or the greatest arrangement is 25.
