Factors of 129

The factors of 129 or the numbers which divide 129 exactly are:

1,3,43, and 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
   

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.
 

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 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

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).
 

• 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.
