Multiple | Common and multiple factors | Various meanings (2023)

In mathematics, we learn different concepts in primary classes. Factors and multiples are important concepts, especially in the reduction and expansion of the factions, and are also used while the standards are found in common, discuss the difference between factors and multipliers with manydissolved examples.

Learn:Factors and multiple

let's go to studyOftenA number in detail here.

What are multiple?

AA result is several times that it is obtained by multiplying a number with an integer(It should not be a fraction) The multiple of the total number will be obtained by removing the product of counting numbers and all numbers.

MultipleThese are useful resources to obtain the large number of certain numbers.

Various Numbers List

A number can have an infinite number of multiples, since multipliers are data multipliers with natural numbers. We can write an infinite number of multipliers for a specific number. The following table shows the first 10 multiple numbers.

Obtain the multiple of some of these numbers with detailed explanations.

Multiple properties

The important properties of the multiples are under the tabular:

Common multiple

Multiple that two numbers are common are called multiple common of these figures. We intend with the help of an example.

Consider two numbers - 30 and 45. Multiples of 30 and 45 are - - - - -

30 = 30, 60, 90, 120, 150, 180, 210, 240, 270… ..

45 = 45, 90, 135, 190, 225, 270 ……….

We see that 90 and 270 are the first two common multiples of 30 and 45.

Suppose Joe and Sam run on a circular route. start point?

This can be derived from the common list several times. Sam and Joe will meet again after 90 minutes.

Usual factors

The factors that are two or more in common are called common factors. How do we find the common factors? See two numbers A and B. Write all A and B factors separately and observe the numbers that A and B are common and understandThe concept of common factors that use an example.

Taking into account the same two numbers 30 and 45.

30 and 45 factors are - - -

30 = {1, 2, 3, 5, 10, 15 E 30}

45 = {1, 3, 5, 9, 15, 45}

What are the common factors you can see? 15, 5, 3 and 1 appear in 30 and 45.

The frequent factors of 30 and 45 are 1, 3, 5 and 15.

This concept has also adopted many practical applications, wishes a dimensional room of 30 m x 45 m. The maximum size of a square mosaic that can be used can be derived with the help of common factors. Square shakes of the lateral length 15 cm.

Coprimon number

Two numbers with "1" are only called cousins as a common factor. Example: 5 and 14, 6 and 17.

Observation:

• Of thePrime numbersThey are always cousin numbers.
• Two uniform numbers can never be co-private numbers.

Difference between factors and multiples

The main difference between factors and multiples is provided below:

Multiple examples resolved

Example 1:

Write the first 5 multiples of individuals of the following.

1. 23 (b) 40

Solution:

(A) The first five multiples of 23 are 23, 46, 69, 92, 115.

Explanation:

1 x 23 = 23

2 x 23 = 46

3 x 23 = 69

4 x 23 = 92

5 x 23 = 115

(B) The first five multiples of 40 are 40, 80, 120, 160, 200

Explanation:

1 x 40 = 40

2 x 40 = 80

3 x 40 = 120

4 x 40 = 160

5 x 40 = 200

Example 2:

Write the factors and multiples of 25.

Solution:

The factors of 25 are 1, 5 and 25

The multiple of 25 is 25, 50, 75, 100, 125, 150 and so on.
