6111 divided by 3 is 2037Originally Posted by Euclid Alexandria
I suspect I'm just drawing a blank here, but I thought any number is divisible by 3 if the sum of its digits is divisible by 3.
Am I wrong about this? I came across the number 6111. The sum of its digits is 9. But when I divide 6111 by 3, I get .
Good question. I was actually part-way through simplifying a fraction when I came across 6111. While subtracting/carrying in the division problem, I suavely made the 1 into a 10 instead of 11, henceOriginally Posted by topsquark
So yeah, it was really a problem w/division
I'm avoiding my calculator at all costs right now. Of course, it seems I'm regressing lately. Moving on to 2037, the sum of its digits is 12. I just tried dividing that by 2, and then tried again, and both times I got
Shouldn't 2 be going evenly into 2037?
By "the pair," I suppose you're referring to
Since 4,753 is a prime number.
Given the restraint of solving by hand, I'm having difficulty determining how I might ascertain the pair's Highest Common Factor... especially if this is the only method available for simplifying this fraction in particular.
