9 is both a factor and multiple of 9, since 1*9 = 9.
A factor is what goes into a number, a multiple is what a number goes into. 3 is a factor of 9 27 is a multiple of 9.
It can be either or both. 36 is a factor of 72. 36 is a multiple of 9. 36 is both a factor and a multiple of 36.
7 & 9 only have one factor in common: 1. So the number which is a multiple of both is 7 x 9 = 63.
3 and 9 both work
Which number is a factor of 10 , but not a multiple of 5
The number is 18, It is even number, it is factor of 198 and multiple of 9
No, 9 is a factor of 36.
If the sum of the digits of a given number equals nine or a multiple of nine, nine is a factor of that number.
Both. 3 is a multiple of 1. 3 is a factor of 9.
I think you might mean "multiple." If the sum of a number's digits is a multiple of 9, the original number is as well. If you want to know how you know if a number is a factor of 9, memorize the numbers 1, 3 and 9.
Any multiple of 36
Both 9 and 36 are multiples of 9 and factors of 36.
189 is a composite. Some quick tests, which can be done in your head: Check if the number is even (2 is a factor). Ones place will have 0,2,4,6, or 8 if even. Multiple of 5 (5 is a factor): Ones digit is 0 or 5. Multiple of 3 or 9: Add up the digits in the number; if this sum is 3 or a multiple of 3, then the original number is a multiple of 3 (3 is a factor). Additionally, if this sum equals 9 or a multiple of 9, then 9 is a factor. This is the case for 189 : 1+8+9=18, which is a multiple of 9. Since we found a factor (in addition to 1 & the original number) then the number is composite and not prime.
No factor of 9 has three digits. 450 is a three-digit multiple of 150 (and of 9) with a digit sum of 9.
3 and 9 both work
As 9 is a multiple of 3, any multiple of 9 will do : 9,18,27,36,45,....
No, 9 is a multiple of 3 but not a factor of 12.
1 is a one-digit number that is a factor of both 8 and 9, but there is no one-digit number that has both 8 and 9 as factors.
No. 9 is a multiple of 3, an equal or larger number which is the product of factors.
450 or 900
No, it's a common factor.
No. As a general rule, multiples cannot be smaller than the number they are compared to. 9 is a factor of 225. 225 is a multiple of 9.
