1 x 81, 3 x 27, 9 x 9, 27 x 3, 81 x 1
Factors of 81 in pairs = 1 x 81, 3 x 27, 9 x 9, 27 x 3, 81 x 1.
Since 81 is not divisible by 7 therefore, 7 is not a factor of 81.
Nine is the highest common factor of 81 and 9
No, 18 is not a factor of 81.
The factor pairs of 26 are the pairs of numbers that, when multiplied together, equal 26. The factor pairs of 26 are (1, 26) and (2, 13). These pairs represent the integer factors of 26.
81 has three factor pairs: 81,1 27,3 9,9
81,127,39,9
1,81,3,27,9
81 and 1 27 and 3
(81,1)(27,3)(9,9)
(81,1)(27,3)(9,9)
(1, 81) (3, 27) (9, 9)
There are 5 factor pairs of 6,561.6561 = 1 x 65616561 = 3 x 21876561 = 9 x 7296561 = 27 x 2436561 = 81 x 81
There are 3 pairs in total 1) 1 and 81 2) 3 and 27 3) 9 and 9
There are 3. 1 x 81, 3 x 27, 9 x 9
Yes, a prime number, P, has only two factor pairs: (1, P) and (P, 1) so immediately after 1, they reverse order.
There is no order to factor pairs: you can present them in any order that you like.
