How do you find the number of positive divisors?
In general, if you have the prime factorization of the number n, then to calculate how many divisors it has, you take all the exponents in the factorization, add 1 to each, and then multiply these “exponents + 1″s together.
What is the integer of 210?
The numbers are 14 and 15 .
Is 210 a composite number?
210 is a composite number, an abundant number, and the product of the first four prime numbers (2, 3, 5, and 7), and thus a primorial. It is the sum of eight consecutive prime numbers (13 + 17 + 19 + 23 + 29 + 31 + 37 + 41 = 210).
How do you find the sum of positive factors of 210?
Answer: . The factors of the number 210 are: 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210. If you add them up, you will get the total of 576..
What is the HCF of 210?
To find the HCF of 210 and 55, we will find the prime factorization of the given numbers, i.e. 210 = 2 × 3 × 5 × 7; 55 = 5 × 11. ⇒ Since 5 is the only common prime factor of 210 and 55. Hence, HCF (210, 55) = 5.
