Prime numbers have two factors. Prime squares have three factors. Square numbers have an odd number of factors but that number varies.
A prime number has exactly two factors: itself and 1.
2 x 3 x 5 x 7 = 210
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).
There isn't one. Negative numbers have prime factors and numbers don't stop. The smallest positive numbers with a prime factor is 2.
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.
It is 7 because as the product of its prime factors they are: 7*151*223 = 235,711
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.
70
It is: 30
How about: 210
How about: 105
