What is GCF of two numbers?

In mathematics GCF or also known as greatest common factor of two or more number is that one largest number which is a factor of those given numbers. It is represented as GCF (256, 6561).

Properties of GCF

  • The GCF of two or more given numbers cannot be greater than any of the given number. Eg- GCF of 256 and 6561 is 1, where 1 is less than both 256 and 6561.
  • GCF of two consecutive numbers is always 1.
  • The product of GCF and LCM of two given numbers is equal to the product of two numbers.
  • The GCF of two given numbers where one of them is a prime number is either 1 or the number itself.

How can we define factors?

In mathematics a factor is a number which divides into another without leaving any remainder. Or we can say, any two numbers that multiply to give a product are both factors of that product. It can be both positive or negative.

Properties of Factors

  • Each number is a factor of itself. Eg. 256 and 6561 are factors of themselves respectively.
  • 1 is a factor of every number. Eg. 1 is a factor of 256 and also of 6561.
  • Every number is a factor of zero (0), since 256 x 0 = 0 and 6561 x 0 = 0.
  • 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, 4, 8, 16, 32, 64, 128, 256 are exact divisors of 256 and 1, 3, 9, 27, 81, 243, 729, 2187, 6561 are exact divisors of 6561.
  • Factors of 256 are 1, 2, 4, 8, 16, 32, 64, 128, 256. Each factor divides 256 without leaving a remainder.
    Simlarly, factors of 6561 are 1, 3, 9, 27, 81, 243, 729, 2187, 6561. Each factor divides 6561 without leaving a remainder.
  • Every factor of a number is less than or equal to the number, eg. 1, 2, 4, 8, 16, 32, 64, 128, 256 are all less than or equal to 256 and 1, 3, 9, 27, 81, 243, 729, 2187, 6561 are all less than or equal to 6561.

Steps to find Factors of 256 and 6561

  • Step 1. Find all the numbers that would divide 256 and 6561 without leaving any remainder. Starting with the number 1 upto 128 (half of 256) and 1 upto 3280 (half of 6561). The number 1 and the number itself are always factors of the given number.
    256 ÷ 1 : Remainder = 0
    6561 ÷ 1 : Remainder = 0
    256 ÷ 2 : Remainder = 0
    6561 ÷ 3 : Remainder = 0
    256 ÷ 4 : Remainder = 0
    6561 ÷ 9 : Remainder = 0
    256 ÷ 8 : Remainder = 0
    6561 ÷ 27 : Remainder = 0
    256 ÷ 16 : Remainder = 0
    6561 ÷ 81 : Remainder = 0
    256 ÷ 32 : Remainder = 0
    6561 ÷ 243 : Remainder = 0
    256 ÷ 64 : Remainder = 0
    6561 ÷ 729 : Remainder = 0
    256 ÷ 128 : Remainder = 0
    6561 ÷ 2187 : Remainder = 0
    256 ÷ 256 : Remainder = 0
    6561 ÷ 6561 : Remainder = 0

Hence, Factors of 256 are 1, 2, 4, 8, 16, 32, 64, 128, and 256

And, Factors of 6561 are 1, 3, 9, 27, 81, 243, 729, 2187, and 6561

Examples of GCF

Sammy baked 256 chocolate cookies and 6561 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 256 and 6561.
GCF of 256 and 6561 is 1.

A class has 256 boys and 6561 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 256 and 6561. Hence, GCF of 256 and 6561 is 1.

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(256, 6561) = ( 256 * 6561 ) / LCM(256, 6561) = 1.

What is the GCF of 256 and 6561?

GCF of 256 and 6561 is 1.
