Factors of 77
Factors of any number are the whole numbers that can divide the number completely. Why are factors important to learn? For mathematical approaches, factors are used in organizing and bringing more efficiency to any task. In this article, let's learn how to solve factors 77 easily.
What are the Factors of 77?
Factors of 77 are those numbers that can divide 77 perfectly. The factors of 77 are:
1,7,11 and 77.
Negative factors of 77: -1, -7, -11, -77.
Prime factors of 77: 7,11
Prime factorization of 77: 7×11
The sum of factors of 77: 1+7+11+77 = 96
How to Find the Factors of 77
For finding factors of 77, 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 77. Let us find the pairs which, on multiplication, yields 77.
1×77=77
7×11=77
From this, we conclude that, factors of 77 are: 1,7,11, and 77.
Finding Factors using Division Method
The division method finds the numbers that evenly divides the given number 77. To find the factors of 77, we have to divide 77 by all possible natural numbers less than 77 and check.
1,7,11,77 are the only factors that the number 77 has. So to verify the factors of 77 using the division method, we just need to divide 77 by each factor.
77/1 =77
77/7 =11
77/11=7
77/77=1
Prime Factors and Prime Factorization
Prime Factorization is the easiest process to find prime factors. It decomposes 77 into a product of its prime integers.
Prime Factors of 77: 7,11.
Prime Factorization of 77: 7×11
Factor tree
The number 77 is written on top and two branches are extended.
Fill in those branches with a factor pair of the number above, i.e., 77.
Continue this process until each branch ends with a prime factor (number).
The first two branches of the factor tree of 77 are 7 and 11.
Factor Pairs
Positive pair factors: (1,77), (7,11)
Negative pair factors: (-1,-77), (-7,-77).
