Analysis:

1 1 = 1 x 1 1, because11is a prime number, the factor is only1and itself1/kloc-.

In primary school mathematics, two positive integers are multiplied, so both numbers are called factors of product, or divisors.

Extended data:

Basic attributes of factor correlation:

1, plural: There are other positive factors besides 1 and itself.

2. 1 has only a positive factor of 1, so it is neither a prime number nor a composite number.

3. If A is a factor of B and A is a prime number, then A is a prime factor of B. ..

4. Two nonzero natural numbers whose common factor is only 1 are called prime numbers.

5. The number of positive factors of 1 nonzero natural number is limited, of which the smallest is1and the largest is itself. The multiples of nonzero natural numbers are infinite.
