A factor is a number that divides a given number into exact parts. Therefore factors of:
27 are: 1,3,9, 27
54 are: 1,2,3,6,9,18,27,54
81 are: 1,3,9,27,81

Common factors for 27,54 and 81 are: 1,3,9,27
Hence the greatest common factor of 27,54 and 81 = 27 (Required Answer)

A

27, 54, and 81?

27 = 3* 3 * 3

54 = 2 * 3 * 3 * 3

81= 3* 3* 3 * 3

The common prime factors of 27,54 and 81 are 3* 3 * 3

Therefore the greatest common factor of 27,54 and 81 = 3* 3 * 3

=27

Factors of 27 = {1,3,9, 27}
Factors of 54 = {1,2,3,6,9,18,27,54}
Factors of 81 = {1,3,9,27,81}

Common factors for 27,54 and 81 ={1,3,9,27}
Hence the greatest common factor of 27,54 and 81 = 27

C

27, 54, and 81

3 27 54 81
3 9 18 27
3 3 6 9
1 2 3

since 3^3 is the number that divides both 27,54 and 81 without leaving a remainder.
Greatest common factor = 3*3*3= 27

Factors of 27 = 3 *3 * 3
factors of 54 = 2 * 3* 3 * 3
factors of 81 = 3 *3 * 3 * 3
from the above, the common factors in the three numbers 27,54,81 are
3 * 3 * 3 = 27
therefore gcf =27

...
S

Greatest common factor is 27
As 27 goes into 27 (once) goes into 54 (twice) and goes into 81(three times) 27 is the largest number divisible by all three

...
B

27. It is a factor of itself, and divides into 54 twice, and in to 81 three times.
