The factors of 30 are: 1, 2, 3, 5, 6, 10, 15, 30 The factors of 81 are: 1, 3, 9, 27, 81 The common factors are: 1, 3
Factors of 30: 1, 2, 3, 5, 6, 10, 15 and 30.Factors of 81: 1, 3, 9, 27 and 81.Common factors are 1 and 3. But 3 is greater than 1 so, GCF(30, 81) = 3.
The factors of 64 are all 2s and the factors of 81 are all 3s. The greatest common factor is 1, since they have no factors in common. ■
Factors of 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60.1 + 20 + 30 = 51
The common factors of 27 and 81 are: 1, 3, 9, and 27

All Factors of 81:1, 3, 9, 27, 81
Factors of 30: 1, 2, 3, 5, 6, 10, 15 and 30.Factors of 81: 1, 3, 9, 27 and 81.Common factors are 1 and 3. But 3 is greater than 1 so, GCF(30, 81) = 3.
81 has these five factors: 1 3 9 27 81.
The positive integer factors of 81 are:1, 3, 9, 27, 81
The factors of 81 are 1, 3, 9, 27, 81. For them to be common, they need to be compared to another set of factors.
Factors are numbers you can multiply together to get another number. 81: 1, 3, 9, 27, 81
Since 9 is a factor of 81, all of its factors are common.
GCD: 27 LCM: 162 All common factors of 81 and 54 are all multiples of their LCM.
