The common factors are: 1, 3
The factors of 21 are: 1, 3, 7, 21.The factors of 42 are: 1, 2, 3, 6, 7, 14, 21, 42.The common factors are: 1, 3, 7, 21
The factors of 21 are: 1, 3, 7, 21.The factors of 84 are: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84.The common factors are: 1, 3, 7, 21
A factor is a divisor - a number that will evenly divide into another number. 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 42 are 1, 2, 3, 6, 7, 14, 21, and 42. The factors of 63 are 1, 3, 7, 9, 21, and 63. The common factors are 1, 3, 7, and 21.
To find the common factors of 42 and 231, we first need to find the prime factorization of each number. The prime factorization of 42 is 2 x 3 x 7, and the prime factorization of 231 is 3 x 7 x 11. The common factors of 42 and 231 are the prime numbers that appear in both factorizations, which are 3 and 7. Therefore, the two common factors of 42 and 231 are 3 and 7.
The prime factors of 105 are 3, 5, and 7.The prime factors of 126 are 2, 3, 3, and 7.Therefore the prime factors that 105 and 126 have in common are 3, and 7.
The factors of 63 are:1, 3, 7, 9, 21, 63The factors of 147 are:1, 3, 7, 21, 49, 147The common factors are:1, 3, 7, 21
The factors of 21 are:1, 3, 7, 21The factors of 49 are:1, 7, 49The common factors are:1, 7
The factors of 15 are 3 and 5. The factors of 21 are 3 and 7. So the common factor is 3.
The common factors of 84 and 105 are: 1, 3, 7, and 21The factors of 84 are: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84.The factors of 105 are: 1, 3, 5, 7, 15, 21, 35, 105.The common factors are: 1, 3, 7, 21
The common factors are: 1, 3
The common factors are: 1, 3, 7, 21.
The factors of 6 are 1, 2, 3, and 6. The factors of 21 are 1, 3, 7, and 21. The common factors of 6 and 21 are 1 and 3, and the GCF is 3.
One number alone can only have factors, it cannot have a 'common' factor. The factors of 1701 are 3, 3, 3, 3, 3 and 7.
1, 3, 7, and 21 are all common factors of 21 and 42.
The common factors of 42 and 273 are 1, 3, 7 and 21.
The factors of 21 are:1, 3, 7, 21The factors of 35 are:1, 5, 7, 35The common factors are:1, 7
