Well, the factors of a prime number is that they only have two factors.
The proper factors of a number do not include one and the number itself.
There is NO number with the most number of factors.
A number that has more than two factors is a composite number whereas a number that has only two factors is a prime number.
"Proper factors" are all of a number's factors except one and the number itself.
Every number has factors. They are endless.
Square numbers have an odd number of factors.
A number with more than two factors is a composite number. A number with exactly two factors is a prime number.
There is no finite limit to the number of factors.
They ARE the same.
if a number has an odd number of factors it would be a perfect square
if a number has an odd number of factors it would be a perfect square
