The smallest prime factors are 2,3,5,7 thus the smallest number would be the product of these will be 210
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).
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 positive integer is 3.
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.
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.
It is 7 because as the product of its prime factors they are: 7*151*223 = 235,711
It is: 30
How about: 210
How about: 105
