Factors are the numbers that divide any given number evenly without 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 1428, how they are used in real life, and tips to learn them quickly.
The numbers that divide 1428 evenly are known as factors of 1428.
A factor of 1428 is a number that divides the number without remainder.
The factors of 1428 are 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 284, 428, 476, 714, and 1428.
Negative factors of 1428: -1, -2, -3, -4, -6, -9, -12, -17, -18, -34, -36, -51, -68, -102, -153, -204, -284, -428, -476, -714, and -1428.
Prime factors of 1428: 2, 3, and 17.
Prime factorization of 1428: 2² × 3² × 17.
The sum of factors of 1428: 1 + 2 + 3 + 4 + 6 + 9 + 12 + 17 + 18 + 34 + 36 + 51 + 68 + 102 + 153 + 204 + 284 + 428 + 476 + 714 + 1428 = 4044
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 1428. Identifying the numbers which are multiplied to get the number 1428 is the multiplication method.
Step 1: Multiply 1428 by 1, 1428 × 1 = 1428.
Step 2: Check for other numbers that give 1428 after multiplying
2 × 714 = 1428
3 × 476 = 1428
4 × 357 = 1428
6 × 238 = 1428
9 × 158 = 1428
12 × 119 = 1428
17 × 84 = 1428
18 × 79 = 1428
Therefore, the positive factor pairs of 1428 are: (1, 1428), (2, 714), (3, 476), (4, 357), (6, 238), (9, 158), (12, 119), (17, 84), (18, 79).
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 as whole numbers as factors. Factors can be calculated by following the simple division method -
Step 1: Divide 1428 by 1, 1428 ÷ 1 = 1428.
Step 2: Continue dividing 1428 by the numbers until the remainder becomes 0.
1428 ÷ 1 = 1428
1428 ÷ 2 = 714
1428 ÷ 3 = 476
1428 ÷ 4 = 357
1428 ÷ 6 = 238
1428 ÷ 9 = 158
1428 ÷ 12 = 119
1428 ÷ 17 = 84
1428 ÷ 18 = 79
Therefore, the factors of 1428 are: 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 284, 428, 476, 714, 1428.
The factors can be found by dividing them with prime numbers. We can find the prime factors using the following methods:
Using Prime Factorization: In this process, prime factors of 1428 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
1428 ÷ 2 = 714
714 ÷ 2 = 357
357 ÷ 3 = 119
119 ÷ 17 = 7
7 ÷ 7 = 1
The prime factors of 1428 are 2, 3, and 17.
The prime factorization of 1428 is: 2² × 3 × 17.
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows -
Step 1: Firstly, 1428 is divided by 2 to get 714.
Step 2: Now divide 714 by 2 to get 357.
Step 3: Then divide 357 by 3 to get 119.
Step 4: Divide 119 by 17 to get 7.
Here, 7 is the smallest prime number, that cannot be divided anymore.
So, the prime factorization of 1428 is: 2² × 3 × 17.
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 1428: (1, 1428), (2, 714), (3, 476), (4, 357), (6, 238), (9, 158), (12, 119), (17, 84), (18, 79).
Negative factor pairs of 1428: (-1, -1428), (-2, -714), (-3, -476), (-4, -357), (-6, -238), (-9, -158), (-12, -119), (-17, -84), (-18, -79).
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 714 apples and 2 baskets. How will they divide it equally?
They will get 357 apples each.
To divide the apples equally, we need to divide the total apples with the number of baskets.
714/2 = 357
A garden is rectangular, the length of the garden is 18 meters, and the total area is 1428 square meters. Find the width?
79 meters.
To find the width of the garden, we use the formula,
Area = length × width
1428 = 18 × width
To find the value of width, we need to shift 18 to the left side.
1428/18 = width
Width = 79.
There are 12 boxes and 1428 marbles. How many marbles will be in each box?
Each box will have 119 marbles.
To find the marbles in each box, divide the total marbles with the boxes.
1428/12 = 119
In a seminar, there are 1428 participants, and 9 groups. How many participants are there in each group?
There are 158 participants in each group.
Dividing the participants with the total groups, we will get the number of participants in each group.
1428/9 = 158
1428 pages need to be bound into 6 books. How many pages will go in each book?
Each book will have 238 pages.
Divide total pages with books.
1428/6 = 238
