Any number and its inverse example 4 x 1/4=1 2x 1/2=1
An even number
You need two numbers to have a product.
A generalization about factors and products for whole numbers is that every whole number greater than one has at least two factors: one and itself. Additionally, the product of two whole numbers is always a whole number, and if both factors are greater than one, their product will also be greater than either factor. This illustrates the foundational relationship between multiplication and the concept of factors in whole numbers.
They are the products of two distinct prime numbers. Along with one and the numbers themselves, they all total four factors.
When one of the numbers is a factor of the other.
Two factors are multiplied to make a product.
Products of prime numbers are composite numbers.
They are the composite numbers, products of primes and their multiples. All even numbers are composite, except the number two (2) which is prime.
The GCF of two numbers is one of the two numbers when one of the numbers is a factor of the other because a number can't have a factor higher than itself.
When one of the numbers is a factor of the other.
One of the numbers is a factor of the other.
The products of non-prime numbers have more than two factors.
