If you are multiplying negative numbers, an odd number of factors will have a negative product. An even number of factors will have a positive product.
The product of any number's prime factors will always be the number. The prime factors of 62 are 2 and 31 - the only number which can be produced by multiplying 2 and 31 is 62.
Factor multiplication is the process of multiplying prime factors. The product of factor multiplication is the number that the prime factors are multipilicands of.
The product will be greater than either of the factors.
Every product of two prime numbers has four factors.
The same way that factoring a number is different from multiplying two factors. In general, it is much easier to multiply two factors together, than to find factors that give a certain product.
A prime number is a number that has only 2 factors, itself, and 1. For multiplying, your product is always a composite number, a number that has 3 or more factors. 1 is neither, 2 is neither.
