Question 1199209
<br>
For this one, you definitely want to use an online calculator to find the prime factorization... unless you have nothing better to do with your time.<br>
454425283 = (13^3)(17^1)(23^3)<br>
You could use the online calculator again to find the prime factorizations of the other two numbers.  But you don't have to, because you already know that<br>
(a^3)(b^3)(c) = (13^3)(17)(23^3),<br>
so you know that c is 17 and a and b are, in some order, 13 and 23.  And since you are only asked to find the sum a+b+c, you have all the information you need to do that.<br>
ANSWER: a+b+c = 13+17+23 = 53<br>
