Multiplying three Factors

Introduction to multiplying three factors:

This article we will discuss about multiplying three factors and factorization methods. Any numbers that when multiplied together form a product called as factors. Each number should have a factors each factor is unique it must not zero. For example 2 is a factor of 8 because 2 can be multiply by 4 to give 8 this is called factors. Lets us see about prime factors, and multiplying three factors.Understanding Prime Factors of 72 is always challenging for me but thanks to all math help websites to help me out.

Factors:

Prime factorization:

A Prime number is a whole number that can be divisible by itself. This called prime number. For Example 1, 3, 5, 7 are some of the prime numbers.

Factorization is finding which prime number need to multiply together it gets the original number. Factoring is to express a number as the product is called factors. Factors are numbers.

Multiplication: repeated addition of number is called multiplication for example   4* 3=12 it just add  4 times of  3 like 4+4+4=12 or 3 times of 4 (3+3+3+3=12) Let us see example of multiplying three factors.

Example1: multiplying three factors 20 * 6 * 18

Solution:

Multiply three factors:

Step 1:   20  *

6   

120

we multiply 20 *6 factors we can get 120 now we multiply 120 * 18.

Step2: 120 *

18  

1960

120  

2160

Step 3: Therefore multiplying three factors 20 * 6 * 18 is 2160

Example2: multiplying three factors 10 * 40 * 8

Solution: 

Multiply three factors

Step 1: multiply 10 * 40

10   *

40   

00

40  

400

If we multiply 10 *40 factors we can get 400 now we multiply 400 * 8.

Step 2: multiply 400 * 8

400 *

8 

3200

Step 3: Therefore multiplying three factors 10 * 40 * 8 is 3200.

Multiply three Factors Using Associative Property:

Associative property means the factors are same on either side of the equal sign and when we multiply two or grouping of factors does not change the product. (a * b) * c = a* (b * c) following example for multiply three factors.

solve:2* 6 * 3

Solution:

multiply 2 * 6 * 3

Step 1: 2 * 6 * 3 = 36

Step 2: apply associative property

2 * (6 * 3)

= 2 * (18)

= 36 when we multiply two or grouping of factors does not change the product.

Step 3: therefore multiplying three factors 2 * 6 * 3 is 36.
