because you have a number times itself 6x6.
No. 81=9*9=3*27=1*81 81 has 5 factors and is a square number. 36=6*6=3*12=1*36=2*18=4*9 36 has 9 factors and is a square number. This doesn't mean that no square numbers have exactly 3 factors though, because: 9=3*3=1*9 9 has 3 factors and is a square number. 4=2*2=1*4 4 has 3 factors and is a square number. All square numbers have an odd number of factors though (because they have a whole number which multiplies by itself to get the number). Factors are whole numbers only, and not decimals. Hope this helps :)
Multiples of 9 that are factors of 36 include 9 and 18. A multiple of a number is any number that can be divided by that number without leaving a remainder. A factor of a number is a number that divides the original number without leaving a remainder. In this case, 9 and 18 are both multiples of 9 and factors of 36 because they can be divided evenly into 36.
