We know that the numbers between 1 and 100 which have exactly three factors are 4, 9, 25 and 49. Factors of 4 are 1, 2 and 4. Factors of 9 are 1, 3 and 9.
How do you know if a number has only 3 divisors?
Given a number N, print all numbers in the range from 1 to N having exactly 3 divisors. Examples: Input : N = 16 Output : 4 9 4 and 9 have exactly three divisors. Divisor Input : N = 49 Output : 4 9 25 49 4, 9, 25 and 49 have exactly three divisors.
What is the number between 40 and 50 with exactly 3 factors?
With that definition, every number with exactly three factors is the square of a prime number. The factors are one, the prime number and the prime number squared (i.e., the number itself). So it’s one of the series 4, 9, 25, 49, 121, 169, 289, 361, 529, … . The only one of those between 40 and 50 is 49.
Is it possible for a number to have multiple factors?
It is possible for a number to have multiple factors. Using 12 as an example, in addition to 3 and 4 being factors: It can be seen that 1, 2, 3, 4, 6, and 12 are all factors of the number 12. This is the most basic form of a factor, but algebraic expressions can also be factored, though that is not the intent of this calculator.
Which is a number with 2 and 3 factors?
24 has 2 and 12, 12 has 2 and 3, so the complete factorization is 2*2*2*3, which is either more than 2 factors, or if you’re using the above weird version, is only two factors. 21 has two factors, 3 and 7. So, 42 is a number that fits requirements
What is the number between 24 and 12 with exactly 3?
24 has 2 and 12, 12 has 2 and 3, so the complete factorization is 2*2*2*3, which is either more than 2 factors, or if you’re using the above weird version, is only two factors. So, either you are wrong about “the” and there are actually two, or else you’re using a weird definition and the answer is 42.
