Factors of 165
Factors of any number are the dividers or multipliers that can divide the number fully and can be multiplied together to produce the given product, 165. Do you know, factors form the basic approach to solve some general mathematical procedures? This article will give you the insights of factors of 165.
What are the Factors of 165?
The factors of 165 or the numbers which divide 165 exactly are:
1,3,5,11,15,33,55, and 165.
Negative factors of 165: -1,-3,-5,-11,-15,-33,-55,-165.
Prime factors of 165: 3,5,11
Prime factorization of 165: 3×5×11
The sum of factors of 165: 1+3+5+11+15+33+55+165= 288
How to Find the Factors of 165
For finding factors of 165, we will be learning these below-mentioned methods:
- Multiplication Method
- Division Method
- Prime Factor and Prime Factorization
- Factor Tree
Finding Factors using Multiplication Methods
This particular method often finds the pair of factors which, on multiplication together, produces 165. Let us find the pairs which, on multiplication, yields 165.
1×165=165
3×55=165
5×33=165
11×15=165
So, factors of 165 are: 1,3,5,11,15,33,55, and 165.
Finding Factors using Division Method
The division method finds the factors that evenly divides the given number 165. In this process, we have to divide 165 by all possible natural numbers less than 165 and check.
1,3,5,11,15,33,55, and 165 are the only factors that the number 165 has. So to verify the factors of 165 using the division method, we just need to divide 165 by each factor.
165/1 =165
165/3=55
165/5=33
165/11=15
165/15=11
165/33=5
165/55=3
165/165=1
Prime Factors and Prime Factorization
Prime Factorization is the easiest process to find prime factors. It decomposes 165 into a product of its prime integers.
Prime Factors of 165: 3,5,11.
Prime Factorization of 165: 3×5×15
Factor tree
The number 165 is written on top and two branches are extended.
Fill in those branches with a factor pair of the number above, i.e., 165.
Continue this process until each branch ends with a prime factor (number).
The first two branches of the factor tree of 165 are 3 and 55, then proceeding to 55, we get 5 and 11. So, now the factor tree for 165 is achieved.
Factor Pairs
Positive pair factors: (1,165), (3,55), (5,33), (11,15).
Negative pair factors: (-1,-154), (-3,-55), (-5,-33), (-11,-15).
