Factors of 129
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, 129. Do you know, factors form the basic approach to solve some general mathematical procedures? This article will give you the insights of factors of 129.
What are the Factors of 129?
The factors of 129 or the numbers which divide 129 exactly are:
1,3,43, and 129.
Negative factors of 129: -1,-3,-43,-129.
Prime factors of 129: 3,43
Prime factorization of 129: 3×43
The sum of factors of 129: 1+3+43+129 = 176
How to Find the Factors of 129
For finding factors of 129, 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 129. Let us find the pairs which, on multiplication, yields 129.
- 1×129=129
- 3×43=129
So, factors of 129 are: 1,3,43, and 129.
Finding Factors using Division Method
The division method finds the factors that evenly divides the given number 129. In this process, we have to divide 129 by all possible natural numbers less than 129 and check.
1,3,43, and 129 are the only factors that the number 129 has. So to verify the factors of 129 using the division method, we just need to divide 129 by each factor.
- 129/1 =129
- 129/3=43
- 129/43=3
- 129/129=1
Prime Factors and Prime Factorization
Prime Factorization is the easiest process to find prime factors. It decomposes 129 into a product of its prime integers.
- Prime Factors of 129: 3,43.
- Prime Factorization of 129: 3×43
Factor tree
The number 129 is written on top and two branches are extended.
Fill in those branches with a factor pair of the number above, i.e., 129.
Continue this process until each branch ends with a prime factor (number).
The first two branches of the factor tree of 129 are 3 and 43.
Factor Pairs
Positive pair factors: (1,129), (3,43).
Negative pair factors: (-1,-129), (-3,-43).
Important Glossaries for Factors of 129
- Multipliers - Number which multiplies or a number by which another number is multiplied.
- Dividers - A number that divides.
- Prime Factorization - It involves factoring the number into its prime factors.
- Prime factors - These are the prime numbers which on multiplication together results into the original number whose prime factors are to be obtained.
- Composite numbers - These are numbers having more than two factors.
- Multiple - It is a product of the given number and any other integer.
