Factors are the numbers that divide any given number evenly without a remainder. In daily life, we use factors for tasks like sharing items equally, arranging things, etc. In this topic, we will learn about the factors of 1390, how they are used in real life, and the tips to learn them quickly.
The numbers that divide 1390 evenly are known as factors of 1390.
A factor of 1390 is a number that divides the number without remainder.
The factors of 1390 are 1, 2, 5, 10, 139, 278, 695, and 1390.
Negative factors of 1390: -1, -2, -5, -10, -139, -278, -695, and -1390.
Prime factors of 1390: 2, 5, and 139.
Prime factorization of 1390: 2 × 5 × 139.
The sum of factors of 1390: 1 + 2 + 5 + 10 + 139 + 278 + 695 + 1390 = 2520
Factors can be found using different methods. Mentioned below are some commonly used methods:
To find factors using multiplication, we need to identify the pairs of numbers that are multiplied to give 1390. Identifying the numbers which are multiplied to get the number 1390 is the multiplication method.
Step 1: Multiply 1390 by 1, 1390 × 1 = 1390.
Step 2: Check for other numbers that give 1390 after multiplying
2 × 695 = 1390
5 × 278 = 1390
10 × 139 = 1390
Therefore, the positive factor pairs of 1390 are: (1, 1390), (2, 695), (5, 278), (10, 139).
All these factor pairs result in 1390.
For every positive factor, there is a negative factor.
Dividing the given numbers with the whole numbers until the remainder becomes zero and listing out the numbers which result in whole numbers as factors. Factors can be calculated by following simple division method
Step 1: Divide 1390 by 1, 1390 ÷ 1 = 1390.
Step 2: Continue dividing 1390 by the numbers until the remainder becomes 0.
1390 ÷ 1 = 1390
1390 ÷ 2 = 695
1390 ÷ 5 = 278
1390 ÷ 10 = 139
Therefore, the factors of 1390 are: 1, 2, 5, 10, 139, 278, 695, 1390.
The factors can be found by dividing it with prime numbers. We can find the prime factors using the following methods:
Using Prime Factorization: In this process, prime factors of 1390 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
1390 ÷ 2 = 695
695 ÷ 5 = 139
139 ÷ 139 = 1
The prime factors of 1390 are 2, 5, and 139.
The prime factorization of 1390 is: 2 × 5 × 139.
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows
Step 1: Firstly, 1390 is divided by 2 to get 695.
Step 2: Now divide 695 by 5 to get 139.
Step 3: Here, 139 is the smallest prime number, that cannot be divided anymore.
So, the prime factorization of 1390 is: 2 × 5 × 139.
Factor Pairs: Two numbers that are multiplied to give a specific number are called factor pairs. Both positive and negative factors constitute factor pairs.
Positive factor pairs of 1390: (1, 1390), (2, 695), (5, 278), and (10, 139).
Negative factor pairs of 1390: (-1, -1390), (-2, -695), (-5, -278), and (-10, -139).
Mistakes are common while finding factors. We can identify and correct those mistakes using the following common mistakes and the ways to avoid them.
There are 10 cars and 1390 miles to cover. How will they distribute the miles equally among the cars?
Each car will cover 139 miles.
To divide the miles equally, we need to divide the total miles by the number of cars.
1390/10 = 139
A rectangular parking area has a length of 278 meters and a total area of 1390 square meters. Find the width.
5 meters.
To find the width of the parking area, we use the formula:
Area = length × width
1390 = 278 × width
To find the value of width, we need to shift 278 to the left side.
1390/278 = width
Width = 5.
There are 695 pieces of fruit and 2 baskets. How many pieces will be in each basket?
Each basket will have 347.5 pieces, but since we cannot have half a piece, we need whole number factors.
To find the fruit in each basket, divide the total pieces by the number of baskets.
1390/2 = 695.
Therefore, each basket can have 695 pieces.
In a warehouse, there are 1390 boxes and 5 sections. How many boxes are there in each section?
There are 278 boxes in each section.
Dividing the boxes by the total sections, we will get the number of boxes in each section.
1390/5 = 278
1390 books need to be arranged in 10 shelves. How many books will go on each shelf?
Each of the shelves will have 139 books.
Divide total books by the number of shelves.
1390/10 = 139
