Date: 01/28/2006 at 23:09:18 From: Doctor Ricky Subject: Re: Hi Cookie, Thanks for writing Dr. Math! Actually there are an infinite number of numbers with only two prime factors and no repeated factors. To find one, think of two prime numbers. Now multiply them together once (so there are no repeated factors). Your result is a number with only two prime factors and no repeated factors. :-) Example: Pick two prime numbers. How about 2 and 3? Now, multiply them together once. 2*3 = 6 Therefore, 6 has only two prime factors and no repeated factors. If you have any questions or if this was a little confusing, please let me know! - Doctor Ricky, The Math Forum http://mathforum.org/dr.math/ |
