Kai wrote the number 85 on the board. Is 85 prime or composite?

Sagot :

A prime number has only two factors . ..  ' 1 ' and itself.

If we can find any other factors of 85 besides ' 1 ' and 85,
then it's not prime.  Let's check:

The factors of 85 are    1,  5,  17,  and  85 .

Each of these numbers divides into 85 evenly (with no remainder).

So I guess it's a composite number.

Hello there! ◉‿◉

85 is a composite number.

A prime number is divisible by only two numbers -  1 and itself.

Examples of prime numbers are: 2, 3, 5, 7, 11, 13...

Composite numbers have 3 or more factors.

85 has more than 3 factors.

Therefore, 85 is a composite number.

Hope this helps you!
