A number is called a factor when it can divide evenly into another number with no remainder. Integers only.
If you are talking about the number itself, they can be the same. To be specific: A prime number is a number that only has the factors 1 and itself. A factor is a number that when multiplied creates a product. A prime factor is a prime number that is multiplied to create a product.
There is no number that can only be multiplied by one.
It is called unity.
The index or the exponent - but only if it is a non-negative integer.
a prime number
No. A "factor" is an integer by which the number is evenly divisible. There is no whole integer that can be multiplied by 20 to equal 24 (only a fraction or decimal).
They have a converse relationship. A factor is a number that divides into another, with no remainders. A multiple is something that can be multiplied by another number, to reach the original number that you had. Thus: Original number / a factor = a multiple Multiple * (the correct factor) = original number. "the correct factor", because most number have more than one factor. But only one factor * multiple will give the original number.
One is a special number because it is neither prime nor composite. It only has one factor, which is one. It can also be multiplied to any number to not change the product from the original number.
Any and every factor can be multiplied by one, so there is no special name.
The only number with a single factor is ' 1 '. Every other number has at least two factors: ' 1 ' and itself. A number with only those two factors and no others is called a "prime" number.
The greatest common factor of 11 is 11 itself. This is because the only whole numbers that can be multiplied in order to come up with the number 11 are 1 and 11.
One is the only number that is a factor of every other number.
No because the number is being squared, not multiplied by its inverse. An identity property is only when a number is multiplied by its inverse.
prime * * * * * No, the only number with just one factor is 1. Each prime has TWO factors: 1 and the prime itself.
a number that can only be multiplied by 1
18 is a composite number because a prime number can only be multiplied by 1 and itself. 18 can be multiplied by 9 and 2 also.
Small words make a difference. No prime number "has" a factor of 16. But 2 is the only prime number that "is" a factor of 16.
The number one is only multiplied by itself.
Only if the rational number is 0.
No prime number only has one factor. Each prime number has itself and 1 as factors. Now, the number 1 of course has only one factor, but it is technically not a prime number.
The only number with one factor is 1.
1 has one factor.
