first three common factors of 3,4,5
9 and 21 only have two common factors: 1 and 3.
The common factors are: 1, 2, 3, 4, 6, 12
Sorry, only two common factors! The common factors are: 1, 3
The common factors of 12 and 15 are 1 and 3.
The common factors of 15, 45, and 75 are the numbers that can evenly divide all three of these numbers. To find the common factors, you can first determine the prime factors of each number: 15 = 3 x 5, 45 = 3 x 3 x 5, and 75 = 3 x 5 x 5. The common factors are the numbers that appear in the prime factorization of all three numbers, which in this case are 3 and 5.
Nine has three factors.
the first three multiples of 3 and 11 is 33,66,and 99.
First, find the factors: 90 = 2*3*3*5 81 = 3*3*3*3 Common factors are 3*3 = 9.
The three common factors of 72, 36, and 24 are 1, 2, and 3. These numbers can divide each of the three values without leaving a remainder. Additionally, the greatest common factor among these numbers is 12, which is the largest of their common factors.
Common factors of 99 and 33 are: 1, 3, 11, and 33.
If that's 12, 18 and 24, 1, 2, 3 and 6 are common factors of all three.
Since 9 is a factor of 27, all of its factors are common.
