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. 66 and 88 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, 11, 22, 33, 66 are exact divisors of 66 and 1, 2, 4, 8, 11, 22, 44, 88 are exact divisors of 88.
- 1 is a factor of every number. Eg. 1 is a factor of 66 and also of 88.
- Every number is a factor of zero (0), since 66 x 0 = 0 and 88 x 0 = 0.
Steps to find Factors of 66 and 88
- Step 1. Find all the numbers that would divide 66 and 88 without leaving any remainder. Starting with the number 1 upto 33 (half of 66) and 1 upto 44 (half of 88). The number 1 and the number itself are always factors of the given number.
66 ÷ 1 : Remainder = 0
88 ÷ 1 : Remainder = 0
66 ÷ 2 : Remainder = 0
88 ÷ 2 : Remainder = 0
66 ÷ 3 : Remainder = 0
88 ÷ 4 : Remainder = 0
66 ÷ 6 : Remainder = 0
88 ÷ 8 : Remainder = 0
66 ÷ 11 : Remainder = 0
88 ÷ 11 : Remainder = 0
66 ÷ 22 : Remainder = 0
88 ÷ 22 : Remainder = 0
66 ÷ 33 : Remainder = 0
88 ÷ 44 : Remainder = 0
66 ÷ 66 : Remainder = 0
88 ÷ 88 : Remainder = 0
Hence, Factors of
66 are 1, 2, 3, 6, 11, 22, 33, and 66
And, Factors of
88 are 1, 2, 4, 8, 11, 22, 44, and 88
Examples of GCF
Sammy baked 66 chocolate cookies and 88 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 66 and 88.
GCF of 66 and 88 is 22.
A class has 66 boys and 88 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 66 and 88. Hence, GCF of 66 and 88 is 22.
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.
Ram has 66 cans of Pepsi and 88 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 66 and 88. Hence GCF of 66 and 88 is 22. So the number of tables that can be arranged is 22.
Ariel is making ready to eat meals to share with friends. She has 66 bottles of water and 88 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 66 and 88. So the GCF of 66 and 88 is 22.
Mary has 66 blue buttons and 88 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 66 and 88. Hence, the GCF of 66 and 88 or the greatest arrangement is 22.
Kamal is making identical balloon arrangements for a party. He has 66 maroon balloons, and 88 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 66 and 88. So the GCF of 66 and 88 is 22.
Kunal is making baskets full of nuts and dried fruits. He has 66 bags of nuts and 88 bags of dried fruits. He wants each basket to be identical, containing the same combination of bags of nuts and bags of driesn fruits, with no left overs. What is the greatest number of baskets that Kunal can make?the greatest number of baskets that Kunal can make would be equal to GCF of 66 and 88. So the GCF of 66 and 88 is 22.
To energize public transportation, Abir needs to give a few companions envelopes with transport tickets, and metro tickets in them. On the off chance that he has 66 bus tickets and 88 metro tickets to be parted similarly among the envelopes, and he need no tickets left. What is the greatest number of envelopes Abir can make?To make the greatest number of envelopes Abir needs to find out the GCF of 66 and 88. Hence, GCF of 66 and 88 is 22.
