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. 486 and 316 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, 27, 54, 81, 162, 243, 486 are exact divisors of 486 and 1, 2, 4, 79, 158, 316 are exact divisors of 316.
- 1 is a factor of every number. Eg. 1 is a factor of 486 and also of 316.
- Every number is a factor of zero (0), since 486 x 0 = 0 and 316 x 0 = 0.
Steps to find Factors of 486 and 316
- Step 1. Find all the numbers that would divide 486 and 316 without leaving any remainder. Starting with the number 1 upto 243 (half of 486) and 1 upto 158 (half of 316). The number 1 and the number itself are always factors of the given number.
486 ÷ 1 : Remainder = 0
316 ÷ 1 : Remainder = 0
486 ÷ 2 : Remainder = 0
316 ÷ 2 : Remainder = 0
486 ÷ 3 : Remainder = 0
316 ÷ 4 : Remainder = 0
486 ÷ 6 : Remainder = 0
316 ÷ 79 : Remainder = 0
486 ÷ 9 : Remainder = 0
316 ÷ 158 : Remainder = 0
486 ÷ 18 : Remainder = 0
316 ÷ 316 : Remainder = 0
486 ÷ 162 : Remainder = 0
486 ÷ 243 : Remainder = 0
486 ÷ 486 : Remainder = 0
Hence, Factors of
486 are 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, and 486
And, Factors of
316 are 1, 2, 4, 79, 158, and 316
Examples of GCF
Sammy baked 486 chocolate cookies and 316 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 486 and 316.
GCF of 486 and 316 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(486, 316) = ( 486 * 316 ) / LCM(486, 316) = 2.
What is the GCF of 486 and 316?GCF of 486 and 316 is 2.
Ram has 486 cans of Pepsi and 316 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 486 and 316. Hence GCF of 486 and 316 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 486 pizzas and 316 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 486 and 316. Thus GCF of 486 and 316 is 2.
Ariel is making ready to eat meals to share with friends. She has 486 bottles of water and 316 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 486 and 316. So the GCF of 486 and 316 is 2.
Mary has 486 blue buttons and 316 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 486 and 316. Hence, the GCF of 486 and 316 or the greatest arrangement is 2.
Kamal is making identical balloon arrangements for a party. He has 486 maroon balloons, and 316 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 486 and 316. So the GCF of 486 and 316 is 2.
