What factors do 16 and 24 have in common?
The common factors of 16 and 24 are: 1, 2, 4, and 8.
What are the factors of 16 and 24?
The factors of 16 and 24 are 1, 2, 4, 8, 16 and 1, 2, 3, 4, 6, 8, 12, 24 respectively. There are 3 commonly used methods to find the HCF of 16 and 24 – Euclidean algorithm, prime factorization, and long division.
How do you know if k is a multiple of 16?
If k were a multiple of 16, it would contain the prime factors of 16: 2, 2, 2, and 2. Thus, if k is a multiple of 24 but not of 16, k must contain 2, 2, and 2, but not a fourth 2 (otherwise, it would be a multiple of 16). Thus: k definitely has 2, 2, 2, and 3.
Which number is a multiple of 24 but not 16?
The smallest number which is a multiple of 24 but not of 16 is 24. In this case k/9, k/32,k/36 or k/81 are not integers. Next number 72 is multiple of 24 but not of 16. In this case k/32 and k/81 will not be integers.
What is the product of any number of factors of 4k+1?
Multiplying two such yields (4k+1)(4m+1) = 4(4km+k+m) +1, another 4k+1. Thus the product of any number of factors of the form 4k + 1 must be another 4k + 1. Thus a 4k + 3 must have a prime factor of the form 4k + 3. Prove that any positive integer of the form 6k + 5 must have a prime factor of the same form.
