Best ResponseYou've already chosen the best response.0Greatest common factor is the biggest multiple, so what do you think it is?

Best ResponseYou've already chosen the best response.2Factors of 18: 1, 2, 3, 6, 9, 18 Factors of 15: 1, 2, 5, 15 The greatest factor both 18 and 15 have is 3. Now do the same for the other choices.

Best ResponseYou've already chosen the best response.0When you find the greatest common factor for two numbers, you lost the numbers they have in common. For question C, The only factors of 6 is 1, 2, 3, 6 The only factors of 9 is 1, 3, 9 Now they each have two numbers in common. 1, and 3. Now decide which of the factors is larger. That is your greatest common factor.
