Factors of 145
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, 145. Do you know, factors form the basic approach to solve some general mathematical procedures? This article will give you the insights of factors of 145.
What are the Factors of 145?
The factors of 145 or the numbers which divide 145 exactly are:
1,5,29, and 145.
- Negative factors of 145: -1,-5,-29,-145.
- Prime factors of 145: 5,29
- Prime factorization of 145: 5×29
- The sum of factors of 145: 1+5+29+145= 180
How to Find the Factors of 145
For finding factors of 145, 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 145.
Let us find the pairs which, on multiplication, yields 145.
1×145=145
5×29=145
So, factors of 145 are: 1,5,29, and 145.
Finding Factors using Division Method
The division method finds the factors that evenly divides the given number 145. In this process, we have to divide 145 by all possible natural numbers less than 145 and check.
1,5,29, and 145 are the only factors that the number 145 has. So to verify the factors of 145 using the division method, we just need to divide 145 by each factor.
145/1 =145
145/5=29
145/29=5
145/145=1
Prime Factors and Prime Factorization
Prime Factorization is the easiest process to find prime factors. It decomposes 145 into a product of its prime integers.
- Prime Factors of 145: 5,29.
- Prime Factorization of 145: 5×29
Factor tree
The number 145 is written on top and two branches are extended.
Fill in those branches with a factor pair of the number above, i.e., 145.
Continue this process until each branch ends with a prime factor (number).
The first two branches of the factor tree of 145 are 5 and 29.
Factor Pairs
Positive pair factors: (1,145), (5,29)
Negative pair factors: (-1,-145), (-5,-29).
