What is the smallest number that is divisible by the numbers 315, 455, and 875. Can you show me how to get this answer?

Answer 1

315 = 3^2 * 5 * 7
455 = 5 * 7 * 13
875 = 5^3 * 7

So, any number divisible by all three of these values must contain all of the factors in any of them. That means that

LCM(315,455,875) = 3^2 * 5^3 * 7 * 13 = 102375
