They can be. 4 and 10 are common factors of 20 and 40.
The common factors of 4 and 10 are 1 and 2.
The factors of 4 are 1, 2, and 4. The factors of 10 are 1, 2, 5, and 10. The common factors of 4 and 10 are 1 and 2. This means 2 is the greatest common factor (GCF), and 2 is the only significant common factor, since all numbers have 1 as a factor.
Common factors of 4 and 10 are: 1 and 2.
The factors of 8 are: 1, 2, 4, 8.The factors of 10 are: 1, 2, 5, 10.The common factors are: 1, 2
The common factors of 20 and 60 are: 1, 2, 4, 5, 10, and 20 The common factors of 20 and 60 are: 1, 2, 4, 5, 10, and 20.
It is two.
The factors of 8 are:1, 2, 4, 8The factors of 10 are:1, 2, 5, 10The common factors are: 1, 2
I am guessing you want common factors. That is to say factors common to 10 and 30 The common factors would be: 1,2, 5, and 10, but there only 4 that are common. 15 and 30 are factors of 30 so if you add those you have 6 factors.
The common factors of 40 and 60 are: 1, 2, 4, 5, 10, 20.The factors of 40 are:1, 2, 4, 5, 8, 10, 20, 40The factors of 60 are:1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60The common factors are: 1, 2, 4, 5, 10, 20
The common factors of 60 and 80 are 1, 2, 4, 5, 10 and 20.
The common factors of 40 and 60 are: 1, 2, 4, 5, 10, 20.
