Factors of 784
In mathematics, a factor of a number can be obtained by checking divisibility by all prime numbers less than or equal to square root of the number. In our daily life, we use factors in arranging any items, or managing time or for sharing any objects. You will learn more about factors of 784 in this article.
What are the factors of 784?
The factors of 784 are 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392 and 784.
Negative factor pairs are the pairs of negative integers that multiply to result in the original number.
Negative Factors of 784: -1, -2, -4, -7, -8, -14, -16, -28, -49, -56, -98, -112, -196, -392 and -784.
Prime factors of 784: 2 and 7.
Prime Factorization of 784: Prime factorization is a process of breaking down any number as the product of prime factors, like in this case it is written as 24 × 72
How to Find the Factors of 784
You need to understand that to find the factors of number, there are a lot of methods. Methods given below are simple ways to find factors:
- Multiplication Method
- Division Method
- Prime Factor and Prime Factorization
- Factor Tree
Finding Factors Using Multiplication Method
Find pairs of numbers that should multiply together to result in the original number.
The pairs are:
1 × 784 = 784
2 × 392 = 784
4 × 196 = 784
7 × 112 = 784
8 × 98 = 784
14 × 56 = 784
16 × 49 = 784
28 × 28 = 784
The factors of 784: 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392 and 784.
Finding Factors Using Division Method
In this division method, you need to find the numbers which divide the original number.
Check the divisibility until 28.
784 / 1 = 784
784 / 2 = 392
784 / 4 = 196
784 / 7 = 112
784 / 8 = 98
784 / 14 = 56
784 / 16 = 49
784 / 28 = 28
The above division calculation shows the factors of 784: 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392 and 784.
Prime Factors and Prime Factorization
Prime factors of 784: 2 and 7
Prime Factorization of 784: Written as 24 × 72 (or) 2×2×2×2×7×7.
Prime factorization is to express any number as a product of prime factors in exponential form.
Factor Tree
Factor tree is a graphical representation of a number into simple prime factors.
Factor Pairs
Positive and Negative factor pair
Positive factor pair — The pair of numbers whose product results in the number itself.
Negative factor pairs — The negative numbers that multiply together to result in a particular product.
Positive factor pair — (1, 784), (2, 392), (4, 196), (7, 112), (8, 98), (14, 56), (16, 49), (28, 28)
Negative factor pair — (-1, -784), (-2, -392), (-4, -196), (-7, -112), (-8, -98), (-14, -56), (-16,- 49), (-28, -28)
Common mistakes and how to avoid them in factors of 784
Kids sometimes make mistakes while finding the factors. You can refer to the solutions to solve these common mistakes that are given below.
Mistake 1
Considering factors as multiples
Students sometimes used to consider multiples of numbers as factors, which leads to wrong answers. To avoid such mistakes, they need to be familiar with the concept of factors of a number.
Factors of 784 Examples
Problem 1
Find the GCF of factors 56 and 784
56
Explanation
GCF of 56 and 784 = 2 × 2 × 2 × 7× 7
= 56
The GCF of 56 and 784 is 56 because all factors of 56 divide 784 evenly.
Problem 2
Find the common factors of 784 and 800
1, 2, 4, 8, and 16.
Explanation
The factors of the numbers 784 and 800
Factors of 784 = 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392 and 784.
Factors of 800 = 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800.
Step 2: Write down the common factors of both number 784 and 800.
The common factor = 1, 2, 4, 8, and 16.
