Question

How many factors of 3 does the number 135 have?

Answer 1

Answer:Prime factorization:

135 = 3 x 3 x 3 x 5, which can also be written 135 = 3³ x 5. 1 + 3 + 5 = 9. Nine is a multiple of both 3 and 9, so this quick divisibility trick lets us know that both 3 and 9 are factors of 135. 135 = 1⁵ x 3³ x 5¹.

Answer 2

The answer is three times 3.

Explanation:

In order to determine the answer, we have to know about factorization.

Any number can be expressed by prime numbers. The procedure is:

• if the number is even, to divide the number by the first prime number, 2.
• if the number is odd, to divide the number by some odd prime number.

In this case, we need to know how many factors of 3 have the number.

`135/3=45\\45/3=15\\15/3=5\\5/5=1\\\\135=3^3*5`

As we can see, there are three times the factor 3.

Finally, the answer is three times 3.
