1 and 3
The only common factor of all three numbers is 3. (The numbers 21 and 63 share all of the factors of 21 : 1, 3, 7, and 21.)
The common factors of 12 and 14 are 1 and 21 and 2
The common factors are: 1, 3
21 and 25 share no common factors aside from 1.
The factors of 21 are:1, 3, 7, 21The factors of 350 are:1, 2, 5, 7, 10, 14, 25, 35, 50, 70, 175, 350The common factors are:1, 7
1 and 3
21 and 22 share no common factors aside from 1.
21 and 50 share no common factors aside from 1.
Assuming you mean 9, 12 21... The only factors that all three numbers share are 1 & 3.
The only common factor of all three numbers is 3. (The numbers 21 and 63 share all of the factors of 21 : 1, 3, 7, and 21.)
The common factors of 12 and 21 are 1 and 3. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 21 are 1, 3, 7, and 21. The common factors are 1 and 3. This means that the greatest common factor is 3. The numbers are 1 and 3
The common factors of 12 and 14 are 1 and 21 and 2
The common factors are: 1, 3
The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 21 are 1, 3, 7, and 21. The common factors are 1 and 3. Therefore, the least common factor (the smallest common factor) is 1.
The common factors of 12 and 21 are 1 and 3.
The factors of 12 are:1, 2, 3, 4, 6, 12The factors of 21 are:1, 3, 7, 21The Greatest Common Factor:GCF = 3
The common factors of 6, 12, and 30 are 1 and 3
