So, you had done everything right so far (other than squaring the 2), but that was only half of the question.
to find the least common multiple, you need to first figure out what the prime factors have in common.
each have two twos. both have one 5, so we know our answer will look something like
now to figure out the other stuff... we have to represent the greatest amount of everything that is left, and we have 3s and 7s left over, so we need to figure out how many of each we need.
one has one 3 and one has two, so we need two threes. now our equation is
what's the only number we have to deal with? 7...
how many sevens does 60 have? 0, and 630 has 1, so we know we need one 7. our answer becomes

Answer:
Step-by-step explanation:
The compounding formula for this is
where A(t) is the amount after all the compounding is done, P is the initial investment, r is the interest rate as a decimal, n is the number of times the interest compounds per year, and t is the time in years. For us, our n is 2, since the money compounds every 6 months, and 6 months goes into 1 year 2 times. Our formula then is:
which simplifies a bit to
which simplifies a bit more to
Raise 1.06 to the power of 18 and then multiply the 2 numbers together:
A(t) = 823(2.854339153) so
A(t) = 2349.12
