the factors of 42 are 1,42,6,7,2,21,3,14
To find the Highest Common Factor (HCF) of 42, 77, and 84, you first need to find the prime factors of each number. The prime factors of 42 are 2, 3, and 7. The prime factors of 77 are 7 and 11. The prime factors of 84 are 2, 3, and 7. To find the HCF, you need to identify the common prime factors and multiply them together. In this case, the HCF of 42, 77, and 84 is 7.
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.
