Can someone help me to understand this? Based on (n)(n+1)(n+2), one of the integer can either be divided by 2 or 3 because the sequence will cover at least an odd or even integer, but why 6? Also can someone point me to the relevant prep swift video related to this topic? Unsure where this one sits.
If a number is divisible by 2 and 3, can you see why it has to be divisible by 6?
I would recommend looking at the “Divisible by 2, 3 …” videos on PrepSwift.
Thank you. I get the theory ie if a number / 6, and the number passes the rule related to 2 (UD / 2) and 3 (sum of digits / 3), it is divisible by 6. But couldn’t relate this with the question
The question is asking what the product of three consecutive numbers must be divisible by. We know that the number must be divisible by 2 and 3. It works the same way - think about divisibility rather than looking at the algebra.
