What is the next number after 22 find the next number after 22 that has exactly 4 factors?
26
A number is three times the sum of its digit find the number?
Is this exactly how the problem was written?
Are one two and nine factors?
That depends what number you are trying to find the factors of - all those three numbers are factors of the number 18.
Find all numbers less than 50 that have exactly three factors?
4, 9, 25, 49
What is the least positive integer that has exactly 13 factors?
4096 is the smallest number with exactly 13 factors. (Including 1 and itself as factors).192 is the smallest number with exactly 13 properfactors, (excluding the number itself).120 is the smallest number with at least 13 factors (it has 16 factors)To find the smallest number with exactly N factors (for example, N=12):Factor N into primes, (for example, 12= 2*2*3Subtract 1 from each of the prime factors (for example, 1,1,2)Sort them by largest first (for example, 2,1,1)Raise successive prime numbers to these powers (for example, 2^2,3^1,5^1)Multiply these together (for example: 4*3*5 = 60; 60 is the smallest number with exactly 12 factors).
How many whole numbers have exactly three digits how did you find that out and tell me why that's the answer?
Assuming that 001, 080, etc are not allowed (that is a leading zero or two is not permitted), the smallest number with exactly three digits is 100. The largest number with exactly three digits is 999. So there are 999 - 100 + 1 = 900 numbers with exactly three digits.
How can you find the factors of a number?
you can by starting with one and ask yourself, is this a factor? Then two, then three ect....
How do you find all positive integers N such that the product 2029 x N has exactly three divisors?
There is only 1 value of N that satisfies 2029 x N has exactly three divisors: N = 2029 To have exactly three divisors, the number must be the square of a prime number. 2029 is a prime number with exactly 2 divisors (1 and 2029). Thus the only number with exactly three divisors of which two are 1 and 2029 is 20292 (= 4116841), making N = 2029.
Can you give you some prime number answers like 127 what two factors does it haveand like these what two factors do these have157 131?
Every prime number has exactly two factors. One of the factors is ' 1 '.The other factor is the number itself. If the number has any more factors,then it's not a prime number.If someone gives you a number, guarantees that it's definitely a prime number,and asks you to find the factors, you know the answer immediately. There aretwo factors. One of the factors is ' 1 ', the other factor is the number itself, andthere are no more factors.
Find a 3 digit number which has only three prime factors?
3 x 5 x 7 = 105
How do you find prime and composite numbers?
By factoring them. Prime numbers have only two factors. Composite numbers have three or more.
How can you determine whether a counting number is a composite number?
Start looking for factors; you already know that 1 is a factor, and that the number itself is a second factor (unless the number is 1). As soon as you find a factor that is neither 1 nor the number itself, the number is composite. If you find exactly two factors, the number is prime. If the number has only one factor, the number is 1, which is neither prime nor composite.
