Q: What are all the factor pairs for 81?

Write your answer...

81 has three factor pairs: 81,1 27,3 9,9

Three factor pairs

(1, 81) (3, 27) (9, 9)

1 x 813 x 279 x 9

1 x 813 x 279 x 9

81 and 1 27 and 3

81,127,39,9

(81,1)(27,3)(9,9)

(81,1)(27,3)(9,9)

Factors of 81 in pairs = 1 x 81, 3 x 27, 9 x 9, 27 x 3, 81 x 1.

There are 3 pairs in total 1) 1 and 81 2) 3 and 27 3) 9 and 9

1,2,3,4,6,8,9,12,18,24,36,72 factor of 72 1,3,9,27,and 81 is factor of 81

The factor pairs are 1•41

There are 3. 1 x 81, 3 x 27, 9 x 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

1x40, 2x20, 4x10, 5x8 are all the factor pairs of 40.

The factor pairs are all the factors of the number, just listed in pairs.

The factor pairs of 20 are: 20,1 / 10,2 / 5,4

The factor pairs of 20 are: 20,1 / 10,2 / 5,4

1 x 81, 3 x 27, 9 x 9, 27 x 3, 81 x 1

Since 27 is a factor of 81, all of its factors are common.

The factor pairs for 38 are (1, 19) and (2, 38).

The factor pairs of 26 are: 1 × 26 2 × 13
