number exactly, leaving no remainder.<\/p>\n\n\n\n<p><strong>Prime numbers<\/strong> are numbers that have only two factors, 1 and the number itself. Examples of prime numbers are: 2, 3, 5, 7, 11, 13, 17, 19, and so on.<\/p>\n\n\n\n<p>Consider an example. The numbers 1, 2, 3, 6 are factors of the number 6.<\/p>\n\n\n\n<p>Thus, we can say that 2 and 3 are the prime factors of 6 and express 6 as&nbsp;<\/p>\n\n\n\n<p>$6 = 2\\times3$<\/p>\n\n\n\n<p>Here, we expressed 6 as the product of its prime factors.
