Prime numbers, raised to a power, have one more factor than their exponents. The smallest prime number is 2. 210 has eleven factors. 210 = 1024
2 is the least prime number.
30 = 2 x 3 x 5Divide the number by the smallest possible prime until you have only prime factors.30 / 2 = 1515 / 3 = 5The factors are 2 x 3 x 5.

Find the prime factorization. Identify the distinct prime factors. Add them up.
There are only 3 numbers to test if they are prime, that isn't very hard. You can also use the list of 1000 smallest primes.
You have to find the smallest prime number that can go into 76, which is 2 and find out what 76/2 is. The, you would have to take the non-prime number and find the smallest prime number that can go into that, and divide by those to numbers again. The prime number you had with 76, you would keep that and keep dividing the non-prime numbers until you end up with all prime numbers.
The four smallest prime numbers are 2, 3, 5, and 7. Their product is 2 x 3 x 5 x 7 = 210. Thus, the smallest number that is divisible by four different prime numbers is 210.

There are more composite numbers than prime numbers, but there is no prime or composite number so great that you can't find a greater one of either kind.

Prime numbers, raised to a power, have one more factor than their exponents. The smallest prime number is 2. 210 has eleven factors. 210 = 1024
Because the smallest such number is 210.
I find the easiest way to find the prime factorization of any number is to start with the smallest prime number that divides the number. So, for 50, I would start with 2. Now we have 2x25. Since 25 is 52 we find the prime factorization of 50 is 2x5x5.
Suppose you have a number N and you want to find its largest prime factor. It is probably easiest to start at the bottom.Find the smallest prime factor, p.Find its factor pair = N/p.If the second number (= N/p) is a prime, then it is the largest prime factor.if not, replace N by N/p and go back to the top.
