It is because 3 is a factor of 9.
So if 9 is a factor of some number X, then X = k*9 for the factor pair 9 and k
But X = k*9 = k*(3*3) = (k*3)*3 so that X is k*3 times 3 ie it is a multiple of 3.
If one number is a factor of another number, the greatest common factor will be the lesser number. Example: 3 and 9 3 is a factor of 9 3 is a factor of 3 There can be no higher factor of a number than the number itself. Therefore, the GCF of 3 and 9 is 3.
A factor is a number that divides evenly into another number with no remainder. 3 is a factor of 9. 4 is not a factor of 9.
Both 6 and 9 have the number 3 as a prime factor. 6 = 3 x 2 9 = 3 x 3
Yes, every number that's divisible by 9 is divisible by 3
9 is not a prime factor, but it does have one prime factor, which is three. Prime factors are factors of a number that are prime.
No, 3 is a factor of 9.
If one number is a factor of another number, the greatest common factor will be the lesser number. Example: 3 and 9 3 is a factor of 9 3 is a factor of 3 There can be no higher factor of a number than the number itself. Therefore, the GCF of 3 and 9 is 3.
3 is a factor of the square number 9.
Because 3 is a factor of 9. Any number that has a composite number as a factor will also have that number's factors as factors.
A factor is a number that divides evenly into another number with no remainder. 3 is a factor of 9. 4 is not a factor of 9.
A factor is a number that divides evenly into another number with no remainder. 3 is a factor of 9. 4 is not a factor of 9.
A factor is a number which, when multiplied by another number makes a third number. The factors of 9 are 3 and 3. The factors of 12 are 2, 2 and 3. SO 3 is a common factor of 9 and 12.
Every number except zero is a factor of every other number. Usually this kind of question is intended as a question about integral factors, those that can be paired with another integer to produce the number as a product. In that sense, 9 is not an integral factor of 11, because the paired number with 9 is 11/9, a number that is not an integer.
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.
9
No. 6 has 3 as a factor. 12 has 3 as a factor.
A number that goes in a number.(e.g 3 is a factor of 9)
