Is 3 a factor of 94?
3 is not a factor of 94. To find whether 3 is a factor of 94, you can divide 94 by 3. Your answer would be 31 1/3. You could also add the digits of 94, in which case you would get 13. If the sum of the digits is divisible by 3, the number is, too. In this case, 13 is not divisible by 3, so neither is 94. You could also look at the digits and know almost immediately that 94 is not divisible by 3 because 3 times 3 is nine and 4 cannot be divided by 3 without having a remainder.
What is the similarities and differences between a factor tree and a prime factor tree?
factor trees and prime factor trees are the same thing with different names.
