How do we define GCF?

In mathematics we use GCF or greatest common method to find out the greatest possible positive integer which can completely divide the given numbers. It is written as GCF (1287, 649740).

Properties of GCF

  • The GCF of two given numbers where one of them is a prime number is either 1 or the number itself.
  • GCF of two consecutive numbers is always 1.
  • Given two numbers 1287 and 649740, such that GCF is 39 where 39 will always be less than 1287 and 649740.
  • Product of two numbers is always equal to the product of their GCF and LCM.

How do you explain factors?

In mathematics, a factor is a number or also it can be an algebraic expression that divides another number or any expression completely and that too without leaving any remainder. A factor of a number can be positive or negative.

Examples of GCF

Sammy baked 1287 chocolate cookies and 649740 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 1287 and 649740.
GCF of 1287 and 649740 is 39.

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(1287, 649740) = ( 1287 * 649740 ) / LCM(1287, 649740) = 39.

What is the GCF of 1287 and 649740?

GCF of 1287 and 649740 is 39.

Ram has 1287 cans of Pepsi and 649740 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 1287 and 649740. Hence GCF of 1287 and 649740 is 39. So the number of tables that can be arranged is 39.
