Best ResponseYou've already chosen the best response.0do you have a prime factorization for 1260?

Best ResponseYou've already chosen the best response.0Numbers divisible by 6 are divisible by both 2 and 3, so once you have the prime factors, multiply all of them except the 2s to get the largest number not divisible by 6.

Best ResponseYou've already chosen the best response.0Thanks! @peachpi and @robtobey. But why would I multiply the 3s if you stated that 6 is divisible by 2 and 3? Kinda confused about why you canceled out the 2s to get the answer.

Best ResponseYou've already chosen the best response.0Because 2 and 3 cannot be at the expression at the same time. If they exist at the same time, then the number will be divisible by 6

Best ResponseYou've already chosen the best response.0So why cancel out 2 but not 3? If only one can be present, cant it be 3 also? @Loser66

Best ResponseYou've already chosen the best response.0Because when you cancel 3, the number is not divisible by 6 but it is NOT the largest one.
