What is the definition of factors?
In mathematics, factors are number, algebraic expressions which when multiplied together produce desired product. A factor of a number can be positive or negative.
Properties of Factors
- Each number is a factor of itself. Eg. 18 and 44 are factors of themselves respectively.
- 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, 3, 6, 9, 18 are exact divisors of 18 and 1, 2, 4, 11, 22, 44 are exact divisors of 44.
- 1 is a factor of every number. Eg. 1 is a factor of 18 and also of 44.
- Every number is a factor of zero (0), since 18 x 0 = 0 and 44 x 0 = 0.
Steps to find Factors of 18 and 44
- Step 1. Find all the numbers that would divide 18 and 44 without leaving any remainder. Starting with the number 1 upto 9 (half of 18) and 1 upto 22 (half of 44). The number 1 and the number itself are always factors of the given number.
18 ÷ 1 : Remainder = 0
44 ÷ 1 : Remainder = 0
18 ÷ 2 : Remainder = 0
44 ÷ 2 : Remainder = 0
18 ÷ 3 : Remainder = 0
44 ÷ 4 : Remainder = 0
18 ÷ 6 : Remainder = 0
44 ÷ 11 : Remainder = 0
18 ÷ 9 : Remainder = 0
44 ÷ 22 : Remainder = 0
18 ÷ 18 : Remainder = 0
44 ÷ 44 : Remainder = 0
Hence, Factors of
18 are 1, 2, 3, 6, 9, and 18
And, Factors of
44 are 1, 2, 4, 11, 22, and 44
Examples of GCF
Sammy baked 18 chocolate cookies and 44 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 18 and 44.
GCF of 18 and 44 is 2.
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(18, 44) = ( 18 * 44 ) / LCM(18, 44) = 2.
What is the GCF of 18 and 44?
GCF of 18 and 44 is 2.
Ram has 18 cans of Pepsi and 44 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 18 and 44. Hence GCF of 18 and 44 is 2. So the number of tables that can be arranged is 2.
Rubel is creating individual servings of starters for her birthday party. He has 18 pizzas and 44 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 18 and 44. Thus GCF of 18 and 44 is 2.
Ariel is making ready to eat meals to share with friends. She has 18 bottles of water and 44 cans of food, which she would like to distribute equally, with no left overs. What is the greatest number of boxes Ariel can make?
The greatest number of boxes Ariel can make would be equal to GCF of 18 and 44. So the GCF of 18 and 44 is 2.
Mary has 18 blue buttons and 44 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 18 and 44. Hence, the GCF of 18 and 44 or the greatest arrangement is 2.
Kamal is making identical balloon arrangements for a party. He has 18 maroon balloons, and 44 orange balloons. He wants each arrangement tohave the same number of each color. What is the greatest number of arrangements that he can make if every balloon is used?
The greatest number of arrangements that he can make if every balloon is used would be equal to GCF of 18 and 44. So the GCF of 18 and 44 is 2.
