Factorise 5x + 40
7x - 49
18x + 9
15x - 10

Factorization is:

Given that we have to factor the given expressions

5x + 40

We have to take the greatest common factor out

When we find all the factors of two or more numbers, and some factors are the same then the largest of those common factors is the Greatest Common Factor

Take G.C.F of 5 and 40

The factors of 5 are: 1, 5

The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40

Then the greatest common factor is 5

Factor out 5 from given expression

7x - 49

Similarly, take G.C.F of 7 and 49

The factors of 7 are: 1, 7

The factors of 49 are: 1, 7, 49

Then the greatest common factor is 7

Factor out 7 from given expression

18x + 9

Similarly, take G.C.F of 18 and 9

The factors of 9 are: 1, 3, 9

The factors of 18 are: 1, 2, 3, 6, 9, 18

Then the greatest common factor is 9

Factor out 9 from given expression

15x - 10

Similarly, take G.C.F of 15 and 10

The factors of 10 are: 1, 2, 5, 10

The factors of 15 are: 1, 3, 5, 15

Then the greatest common factor is 5

Factor out 5 from given expression

Thus factorization is found
