If you mean 5 different prime factors, there are none. Multiplying the first five primes, you get 2*3*5*7*11 = 2310. If there is no requirement that the prime factors be different, there are many such numbers, the smallest being 2*2*2*2*2 = 32, and the largest being 2*2*2*5*7 = 280.
A prime number has exactly two factors: itself and 1.
To find the prime factors of a number, divide the number by the smallest prime number as many times as needed, then by the next smallest prime, forming a "factor tree."180 / 2 = 9090 / 2 = 4545 / 3 = 1515 / 3 = 5The prime factors are 2 x 2 x 3 x 3 x 5 or 22 x 32 x 5
The prime factors are: 2 x 2 x 5
All composite numbers have more than 2 factors whereas prime numbers have only 2 factors
70 is the smallest number that has prime factors of 2,5 and 7
Logically, the smallest number with 4 different prime factors would have to be the product of the smallest four prime numbers. So the smallest natural number with four different prime factors is 210 (2*3*5*7).
The smallest number with three different prime factors is 30.
There isn't one. Negative numbers have prime factors and numbers don't stop. The smallest positive numbers with a prime factor is 2.
Starting from beginning we see that 0 has infinite factors so it is a composite number and 1 is neither prime nor composite. The next number is 2 which has only two factors so it is the smallest Prime number.
It is: 30

Well, darling, the smallest number with 2, 5, and 7 as prime factors is 70. You see, 2 x 5 x 7 equals 70, and that's the tiniest number you can whip up with those prime factors. So, there you have it, sweet cheeks, the answer is 70.
The smallest prime number is '2' (TWO).. It is also the only even prime number.
It is 11 which is a prime number whose factors are itself and one
5 and 11
