30 is divisible by 5, but not by 4. So 5 is the factor of 30, but 4 is not.
To find the common factors of 30 and 20, we first list the factors of each number. The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. The factors of 20 are 1, 2, 4, 5, 10, and 20. The factors that are common to both numbers are 1, 2, 5, and 10.
5 and 1 are the only common factors of both 5 and 30. (30 has factors of 1, 2, 3, 5, 6, 10, and 30, and 5 only shares two of these factors, being 5 and 1 respectively). 1 and 5
3, 5 and 6 are factors of 30
no, they both have 5 as factors
6. factors of 12 are 1, 2, 3, 4, 6, and 12. factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30.
The factors of 15 are 1, 3, 5, and 15. The factors of 30 are 1, 2, 3, 5, 6. 10, 15, and 30. The common factors of 15 and 30 are 1, 3, 5, and 15.
The factors of 12 are:1, 2, 3, 4, 6, 12The factors of 30 are:1, 2, 3, 5, 6, 10, 15, 30The common factors are:1, 2, 3, 6
Factors of 30 are: 1, 2, 3, 5, 6, 10, 15, and 30. Factors of 40 are: 1, 2, 4, 5, 8, 10, 20, and 40. Find the greatest factor they both have in common. That is the greatest common factor.
20: 1, 2, 530: 1, 2, 3, 5 1, 2, 4, 5, 10, 201, 2, 3, 5, 6, 10, 15, 30 The factors of 20 are 1, 2, 4, 5, 10, and 20. The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30.The factors of 20 are 1, 2, 4, 5, 10, and 20. The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30.
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 30 and 300 are the numbers that can divide both 30 and 300 without leaving a remainder. The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. The factors of 300 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, and 300. Therefore, the common factors of 30 and 300 are 1, 2, 3, 5, 6, 10, 15, and 30.
The factors of 28 are: 1, 2, 4, 7, 14, 28 The factors of 30 are: 1, 2, 3, 5, 6, 10, 15, 30
