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, 750).

Properties of GCF

  • The GCF of two or more given numbers is always less than the given numbers. Eg- GCF of 225 and 750 is 75, where 75 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, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 125, 150, 250, 375, 750 are exact divisors of 750.
  • 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 750 are factors of themselves respectively.
  • 1 is a factor of every number. Eg. 1 is a factor of 225 and also of 750.

Steps to find Factors of 225 and 750

  • Step 1. Find all the numbers that would divide 225 and 750 without leaving any remainder. Starting with the number 1 upto 112 (half of 225) and 1 upto 375 (half of 750). The number 1 and the number itself are always factors of the given number.
    225 ÷ 1 : Remainder = 0
    750 ÷ 1 : Remainder = 0
    225 ÷ 3 : Remainder = 0
    750 ÷ 2 : Remainder = 0
    225 ÷ 5 : Remainder = 0
    750 ÷ 3 : Remainder = 0
    225 ÷ 9 : Remainder = 0
    750 ÷ 5 : Remainder = 0
    225 ÷ 15 : Remainder = 0
    750 ÷ 6 : Remainder = 0
    225 ÷ 25 : Remainder = 0
    750 ÷ 10 : Remainder = 0
    225 ÷ 45 : Remainder = 0
    750 ÷ 15 : Remainder = 0
    225 ÷ 75 : Remainder = 0
    750 ÷ 25 : Remainder = 0
    225 ÷ 225 : Remainder = 0
    750 ÷ 30 : Remainder = 0
    750 ÷ 50 : Remainder = 0
    750 ÷ 75 : Remainder = 0
    750 ÷ 125 : Remainder = 0
    750 ÷ 150 : Remainder = 0
    750 ÷ 250 : Remainder = 0
    750 ÷ 375 : Remainder = 0
    750 ÷ 750 : Remainder = 0

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

And, Factors of 750 are 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 125, 150, 250, 375, and 750

Examples of GCF

Sammy baked 225 chocolate cookies and 750 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 750.
GCF of 225 and 750 is 75.

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, 750) = ( 225 * 750 ) / LCM(225, 750) = 75.

What is the GCF of 225 and 750?

GCF of 225 and 750 is 75.
