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 1945, how they are used in real life, and tips to learn them quickly.
The numbers that divide 1945 evenly are known as factors of 1945.
A factor of 1945 is a number that divides the number without remainder.
The factors of 1945 are 1, 5, 389, and 1945.
Negative factors of 1945: -1, -5, -389, and -1945.
Prime factors of 1945: 5 and 389.
Prime factorization of 1945: 5 × 389.
The sum of factors of 1945: 1 + 5 + 389 + 1945 = 2340
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 1945. Identifying the numbers which are multiplied to get the number 1945 is the multiplication method.
Step 1: Multiply 1945 by 1, 1945 × 1 = 1945.
Step 2: Check for other numbers that give 1945 after multiplying 5 × 389 = 1945
Therefore, the positive factor pairs of 1945 are: (1, 1945), (5, 389).
All these factor pairs result in 1945.
For every positive factor, there is a negative factor.
Dividing the given numbers with 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 a simple division method
Step 1: Divide 1945 by 1, 1945 ÷ 1 = 1945.
Step 2: Continue dividing 1945 by the numbers until the remainder becomes 0.
1945 ÷ 1 = 1945
1945 ÷ 5 = 389
Therefore, the factors of 1945 are: 1, 5, 389, 1945.
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 1945 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
1945 ÷ 5 = 389
389 is a prime number and cannot be divided further except by itself.
The prime factors of 1945 are 5 and 389.
The prime factorization of 1945 is: 5 × 389.
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows
Step 1: Firstly, 1945 is divided by 5 to get 389. 389 is a prime number, and no further division is possible except by 389 itself. So, the prime factorization of 1945 is: 5 × 389.
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 1945: (1, 1945), (5, 389).
Negative factor pairs of 1945: (-1, -1945), (-5, -389).
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 5 teachers and 1945 students at a school event. How will they divide the students equally among themselves?
They will each handle 389 students.
To divide the students equally, we need to divide the total number of students by the number of teachers.
1945/5 = 389
A rectangular garden has a length of 5 meters and a total area of 1945 square meters. Find the width.
389 meters.
To find the width of the garden, we use the formula,
Area = length × width
1945 = 5 × width
To find the value of width, we need to shift 5 to the left side.
1945/5 = width
Width = 389.
There are 389 chairs and 1945 students. How many students will share each chair?
Each chair will be shared by 5 students.
To find the number of students per chair, divide the total students by the number of chairs.
1945/389 = 5
In a conference, there are 1945 participants, and there are 5 speaker slots. How many participants will be in each speaker's session?
There will be 389 participants in each session.
Dividing the number of participants by the total speaker slots, we will get the number of participants in each session.
1945/5 = 389
1945 books need to be distributed across 5 libraries. How many books will go to each library?
Each library will receive 389 books.
Divide total books by the number of libraries.
1945/5 = 389
