3 - 81
First divide 3 into 81 81 ÷ 3 = 27 so 81 = 3 × 27 Next divide 3 into 27 27 ÷ 3 = 9 so 27 = 3 × 9 and hence 81 =3 × 27 = 3 × 3 × 9 But 9 = 3 × 3 and thus 81 = 3 × 3 × 9 = 3 × 3 × 3 × 3 = 34
Divide both numbers by 9 (a factor of both 72 and 81) and you get 8/9
18/81 = 2/9 (divide top and bottom by the hcf of 18 & 81 = 9)
81/44 has a greatest common factor of 9; divide both top and bottom by 9 81/144 = 9/16
Yes, these numbers: 1, 3, 9, 27, 81.
9 is the largest integer that can divide into both 36 and 81 evenly with no remainder.
The greatest common factor of 81 and 27 is 27. You can only divide 27 by 1, 3, 9, and 27. You can only divide 81 by 1, 3, 9, 27, and 81. 27 is the biggest factor that both of the numbers have.
Divide by 3
The factors of 81 that are between 2 and 10 are 3 and 9.
