101 is the first three-digit prime number.
What is the perfect numberthat is greater than number 30?
The first two are 6 and 28. You'd have to figure a long time to get to the next one, which is 496.
What is the smallest composite number that has three different prime factors?
Just multiply the first three prime numbers together.
What is the smallest number that 360 needs to be multiplied by to get a perfect square?
To find the smallest number that 360 needs to be multiplied by to get a perfect square, we first factorize 360 into its prime factors: 2^3 * 3^2 * 5. To make it a perfect square, we need to pair up these factors. Since 2 and 5 are not paired, the smallest number we need to multiply 360 by is 5, making it 1800 (2^3 * 3^2 * 5^2), which is a perfect square.
What is smallest four digit number not using zero?
The smallest four-digit number not using zero is 1000. In a four-digit number, the first digit cannot be zero, so the smallest possible value for the first digit is 1. The remaining three digits can be any number from 0-9, so the smallest possible four-digit number is 1000.
What is the smallest number that has the first 5 prime numbers as its prime factors?
The first prime numbers are 2, 3, 5, 7, 11. When multiplied together the product is 2310. It is the smallest number that has the first five numbers as its factors.
If a composite number has the first five prime numbers as factors what is the smallest number it could be?
Just multiply the first five prime numbers! 2x3x5x7x11 = 6x35x11 = 210x11 = 2310. Any multiple of this number "has the first five prime numbers as factors", but 2310 is the smallest such number.
What is the smallest number with 6 factors?
Well, honey, the smallest number with 6 factors is 12. You see, it has 1, 2, 3, 4, 6, and 12 as factors, making a grand total of 6 factors. So, there you have it, sweetie, 12 is the winner in the smallest number with 6 factors competition.
What is the smallest three-digit number that has only two factors?

2310 has all of those as factors.
What is the smallest possible number you can make out of 83150?
If 0 can be counted as the first number, then the smallest number is 01358. If 0 cannot be counted as the first number, the the smallest number is 10358.
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).
What is the perfect numberthat is greater than number 30?
The first two are 6 and 28. You'd have to figure a long time to get to the next one, which is 496.
What is the smallest composite number that has three different prime factors?
Just multiply the first three prime numbers together.
What is the smallest number that has 5 different prime factors?
To calculate this interesting number you need to use the five smallest prime numbers. A prime number is one which is not evenly divisible by any other number (except itself and 1). The first prime number is 2. then we have 3, 5, 7, 11, 13, 17 and so on. So, if you multiply 2 x 3 x 5 x 7 x 11 you'll get the smallest number with 5 different prime factors.
What number has 8 factors?
OK, so maybe I'm making a fool of myself; it won't be the first time. Assume positive integers, and assume that 1 (one) is one of the factors. Also assume that any factor is used only once. If factors can be used any number of times then any number answers the question (seven ones and the number). The smallest number with 8 distinct factors is 510510. If you do not count 1 as a factor, the smallest such number is 9699690. In order, the factors would be 1, 2, 3, 5, 7, 11, 13, 17, (19).
