To find the second smallest number that has 12345 as factors, we need to consider the prime factorization of 12345, which is 3 x 5 x 823. The smallest number with 12345 as a factor is 12345 itself. The second smallest number would be obtained by multiplying 12345 by the next smallest prime number after 3 and 5, which is 7. Therefore, the second smallest number with 12345 as factors is 12345 x 7 = 86415.

Let's call the number 'n'. Its factors will be 1, itself and an unknown number. It will need to be a perfect square, and after some trial and error, we will come to the conclusion that it is 1369. The factors are 1, 1369 and 37.
6. Factors are 1, 2, 3, and 6.
4 : with factors 1, 2 and 4

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.
The smallest 3-digit square number is 100, which is the square of 10 (10 x 10). It is the first perfect square that has three digits.
The smallest positive integer is 3.

If you mean 2, 3 and 7 as factors then the smallest number is 42
Since 3 is prime, the factors are 1 and 3.
To determine the smallest number that 396 must be multiplied by to become a square number, we first factor 396 into its prime factors: (396 = 2^2 \times 3^2 \times 11^1). For a number to be a perfect square, all prime factors must have even exponents. Since the exponent of 11 is odd, we need to multiply 396 by 11 to make it even. Therefore, the smallest number to multiply by is 11.
The smallest possible number to get from 3 and 4 as your factors is 12...
Oh, dude, let me break it down for you. So, 7800 is 2^3 * 3 * 5^2 * 13. To make it a square number, each prime factor needs to appear an even number of times. So, the smallest number it must be multiplied by is 2 * 5 * 13, which is 130. Easy peasy lemon squeezy!
The smallest number that has 9 and 12 as factors is 36.
There are none but the smallest 3 digit number is 161
