4.1 / Least Common Multiples
I. The Least Common Multiple (a.k.a. LCM) of
two numbers is the smallest number divisible
by both of the original numbers (see p.224)
e.g., LCM(8,12) = ___
II. Examples (p.229): Exercises #2,4,10,16
III. Methods for Finding LCMs (p.224 & p.226):
1. Check divisibility of multiples of the
larger number by the smaller number
2. Factor both numbers into primes, then
find the product of all the prime factors
using each the greatest number of times
that it occurs in either factorization...
