What are the Factors of 76?

Factors of 76 are those numbers that can divide 76 perfectly. The factors of 76 are:


1,2,4,19,38 and 76.


Negative factors of 76: -1, -2, -4, -19, -38, -76


Prime factors of 76: 2


Prime factorization of 76: 22×19


The sum of factors of 76: 1+2+4+19+38+76= 140

How to Find the Factors of 76

For finding factors of 76, we will be learning these below-mentioned methods:

 

  • Multiplication Method

 

  • Division Method

 

  • Prime Factor and Prime Factorization

 

  • Factor Tree
     
Professor Greenline from BrightChamps

Finding Factors using Multiplication Methods

This particular method often finds the pair of factors which, on multiplication together, produces 76. Let us find the pairs which, on multiplication, yields 76.


1×76=76


2×38=76


4×19=76

Factors of 76 by multiplication method
From this, we conclude that, factors of 76 are:1,2,4,19,38 and 76.
 

Professor Greenline from BrightChamps

Finding Factors using Division Method

The division method finds the numbers that evenly divides the given number 76. To find the factors of 76, we have to divide 76 by all possible natural numbers less than 76 and check.


1,2,4,19,38 and 76 are the only factors that the number 76 has. So to verify the factors of 76 using the division method, we just need to divide 76 by each factor.


76/1 =76


76/2 =38


76/4=19


76/19=4


76/38=2


76/76=1

Prime Factors and Prime Factorization

Prime Factorization is the easiest process to find prime factors. It decomposes 76 into a product of its prime integers.

 

  • Prime Factors of 76: 2.

 

  • Prime Factorization of 76: 2×2×19 = 22×19
Professor Greenline from BrightChamps

Factor tree

The number 76 is written on top and two branches are extended.


Fill in those branches with a factor pair of the number above, i.e., 76.


Continue this process until each branch ends with a prime factor (number).


The first two branches of the factor tree of 76 are 2 and 38, then proceeding to 38, we get 2 and 19. 
    

Factor Pairs:


Positive pair factors:   (1,76), (2,38), (4,19)


Negative pair factors: (-1,-76), (-2,-38), (-4,-19).

Common Mistakes and How to Avoid Them in Factors of 76

Children quite often make silly mistakes while solving factors. Let us see what are the common errors to occur and how to avoid them.
 

Mistake 1

Red Cross Icon Indicating Mistakes to Avoid in This Math Topic

Misconception and confusion about factors with that of multiples.

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

Factors are way different from multiples. You need to understand it clearly that factors are integers which divide a given number evenly, and multiples are the products we get when the original number is multiplied with different numbers.

Problem 3

The area of a rectangle is 76 square units. If the length is 19 units, then what is the measure of its width?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

Area of rectangle: 76 sq units


Factors of 76: 1,2,4,19,38,76


We know that the area of a rectangle is the product of its length and breadth.


Given, length= 19 units


There exists a factor pair of 76, which is (4,19). Hence, width is 4 units. Let’s check it through the formula for area.


So, length×width = area


⇒ 19 × width = 76


⇒ width = 76/19 = 4


Answer: 4 units
 

Explanation

Used the concept of factor pairs for 76 and rechecked using the formula for finding area of a rectangle.
