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. 168 and 280 are factors of themselves respectively.
- 1 is a factor of every number. Eg. 1 is a factor of 168 and also of 280.
- Every number is a factor of zero (0), since 168 x 0 = 0 and 280 x 0 = 0.
- 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, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168 are exact divisors of 168 and 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280 are exact divisors of 280.
- Factors of 168 are 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168. Each factor divides 168 without leaving a remainder.
Simlarly, factors of 280 are 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280. Each factor divides 280 without leaving a remainder. - Every factor of a number is less than or equal to the number, eg. 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168 are all less than or equal to 168 and 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280 are all less than or equal to 280.
Steps to find Factors of 168 and 280
- Step 1. Find all the numbers that would divide 168 and 280 without leaving any remainder. Starting with the number 1 upto 84 (half of 168) and 1 upto 140 (half of 280). The number 1 and the number itself are always factors of the given number.
168 ÷ 1 : Remainder = 0
280 ÷ 1 : Remainder = 0
168 ÷ 2 : Remainder = 0
280 ÷ 2 : Remainder = 0
168 ÷ 3 : Remainder = 0
280 ÷ 4 : Remainder = 0
168 ÷ 4 : Remainder = 0
280 ÷ 5 : Remainder = 0
168 ÷ 6 : Remainder = 0
280 ÷ 7 : Remainder = 0
168 ÷ 7 : Remainder = 0
280 ÷ 8 : Remainder = 0
168 ÷ 8 : Remainder = 0
280 ÷ 10 : Remainder = 0
168 ÷ 12 : Remainder = 0
280 ÷ 14 : Remainder = 0
168 ÷ 14 : Remainder = 0
280 ÷ 20 : Remainder = 0
168 ÷ 21 : Remainder = 0
280 ÷ 28 : Remainder = 0
168 ÷ 24 : Remainder = 0
280 ÷ 35 : Remainder = 0
168 ÷ 28 : Remainder = 0
280 ÷ 40 : Remainder = 0
168 ÷ 42 : Remainder = 0
280 ÷ 56 : Remainder = 0
168 ÷ 56 : Remainder = 0
280 ÷ 70 : Remainder = 0
168 ÷ 84 : Remainder = 0
280 ÷ 140 : Remainder = 0
168 ÷ 168 : Remainder = 0
280 ÷ 280 : Remainder = 0
Hence, Factors of
168 are 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, and 168
And, Factors of
280 are 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, and 280
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(168, 280) = ( 168 * 280 ) / LCM(168, 280) = 56.
What is the GCF of 168 and 280?GCF of 168 and 280 is 56.
