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.
Properties of Factors
- Each number is a factor of itself. Eg. 42 and 504 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, 7, 14, 21, 42 are exact divisors of 42 and 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504 are exact divisors of 504.
- 1 is a factor of every number. Eg. 1 is a factor of 42 and also of 504.
- Every number is a factor of zero (0), since 42 x 0 = 0 and 504 x 0 = 0.
Steps to find Factors of 42 and 504
- Step 1. Find all the numbers that would divide 42 and 504 without leaving any remainder. Starting with the number 1 upto 21 (half of 42) and 1 upto 252 (half of 504). The number 1 and the number itself are always factors of the given number.
42 ÷ 1 : Remainder = 0
504 ÷ 1 : Remainder = 0
42 ÷ 2 : Remainder = 0
504 ÷ 2 : Remainder = 0
42 ÷ 3 : Remainder = 0
504 ÷ 3 : Remainder = 0
42 ÷ 6 : Remainder = 0
504 ÷ 4 : Remainder = 0
42 ÷ 7 : Remainder = 0
504 ÷ 6 : Remainder = 0
42 ÷ 14 : Remainder = 0
504 ÷ 7 : Remainder = 0
42 ÷ 21 : Remainder = 0
504 ÷ 8 : Remainder = 0
42 ÷ 42 : Remainder = 0
504 ÷ 9 : Remainder = 0
504 ÷ 126 : Remainder = 0
504 ÷ 168 : Remainder = 0
504 ÷ 252 : Remainder = 0
504 ÷ 504 : Remainder = 0
Hence, Factors of
42 are 1, 2, 3, 6, 7, 14, 21, and 42
And, Factors of
504 are 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, and 504
Examples of GCF
What is the relation between LCM and GCF (Greatest Common Factor)?GCF and LCM of two numbers can be related as GCF(42, 504) = ( 42 * 504 ) / LCM(42, 504) = 42.
What is the GCF of 42 and 504?GCF of 42 and 504 is 42.
Ram has 42 cans of Pepsi and 504 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 42 and 504. Hence GCF of 42 and 504 is 42. So the number of tables that can be arranged is 42.
Rubel is creating individual servings of starters for her birthday party. He has 42 pizzas and 504 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 42 and 504. Thus GCF of 42 and 504 is 42.
Ariel is making ready to eat meals to share with friends. She has 42 bottles of water and 504 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 42 and 504. So the GCF of 42 and 504 is 42.
Mary has 42 blue buttons and 504 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 42 and 504. Hence, the GCF of 42 and 504 or the greatest arrangement is 42.
