171 is divisible by 9 because its digits add up to 9 i.e. 1+7+1 = 9 and so 171/9 =19
Factors come in pairs. If you know one factor, divide it into the number. The answer will be another factor.
False. Just because a number has 2 and 4 as factors does not necessarily mean it has 8 as a factor. For a number to have 8 as a factor, it must have both 2 and 4 as factors, but it could also have additional factors that are not necessarily present in numbers with only 2 and 4 as factors. In other words, having 2 and 4 as factors is a necessary but not sufficient condition for a number to have 8 as a factor.
