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
To find the smallest common multiple of two numbers, you need to first find their prime factorization. The prime factorization of 1818 is 2 x 3 x 3 x 101, and the prime factorization of 606 is 2 x 3 x 101. To find the smallest common multiple, you take the highest power of each prime factor that appears in either number, which gives you 2 x 3 x 3 x 101, resulting in 1818 as the smallest common multiple of 1818 and 606.
The prime factors of 315 are 3, 3, 5, and 7. To find the prime factors, you can start by dividing 315 by the smallest prime number, which is 2, but since 315 is odd, you move on to the next smallest prime number, which is 3. Dividing 315 by 3 gives you 105, and then further dividing by 3 gives you 35. Finally, dividing 35 by 5 gives you 7, which is a prime number. Therefore, the prime factors of 315 are 3, 3, 5, and 7.
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.
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.
