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

For finding factors of 145, 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 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.
 

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 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

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)
