1, 2, 4, 5, 10, 20, 25, 50, 100
They are: 1, 3 and 9
100.....1,2,4,5,10,20,25,50,100
100 has 9 factors (1, 2, 4, 5, 10, 20, 25, 50, 100), so the one factor 10 is 1/9 of the total number of factors of 100.
first you have your whole number 3. keep that constant. now take the fraction 9/100. make that into a decimal. well 9 out of 100 is equal to 9% and 9% is the same as 0.09 Now take the whole number and put the decimal you got behind the whole number... like this... 3.09 that is your answer
The factors are 1,3,5,9,15,45
36
Prime squares: 4, 9, 25, 49
They are: 1, 3 and 9
36 has nine factors.

The factors are 1,3,5,9,15,45
Every number has 1 as a factor. 6 and 9 are not factors of 1 as they are both greater than 1 and all factors of a number are less than or equal to the number. The least whole number with 6 and 9 as factors is the lowest common multiple of 6 and 9 lcm(6, 9) = 18 6 = 2 × 3 9 = 3² → Lcm = 2 × 3² = 18
