How many factor trees does 67 have?

Answer 1

A factor tree breaks a number down into it's prime numbers.

A Prime number is a number that can only be divided by 1 and itself.
For example: 3 is a prime number, because the only numbers that can be divided evenly into 3 are 1 and 3.

Your number is 77. I can tell by looking at the number that it is divisible by 7 (note the double 7's in 77)

77 / 7 = 11.

This means that 7 * 11 = 77

Your factor tree would look like:

......77
....../ \
.....7*11

Now we see if 7 and 11 can be broken down into smaller prime factors.
Fortunately for us, 7 is already a prime number.
And, as luck would have it, 11 is also a prime number.

This completes the factor tree of 77.

Answer 2

47 is a prime, so

47 = <1> \ <47>

Answer 3

67 is prime, so a factor tree of 67 looks like:

67

(67 can be written as 67 x 1.)

Answer 4

The factor tree is this.

77

/ \

(7) (11)

.

. . 7,11

Make sure to box your answer. This was the factor

tree for 77.

Answer 5

67 is a prime number so prime factorization does not apply.

Answer 6

None. 67 is already prime.

Answer 7

71 is prime. No tree.
