The smallest prime factors are 2,3,5,7 thus the smallest number would be the product of these will be 210
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).
How about: 105
5 and 11
30,030 Factorization: 2x3x5x7x11x13
As a product of its prime factors: 2*3*5*7 = 210
what is the smallest positive integer that has four different prime factors
If a number has 5 factors then it most certainly is not prime. Hence there is some confusion as to what you are asking here.
210 with factors of 2, 3, 5, and 7
210, welcome :D
The smallest number with three different prime factors is 30.
70 is the smallest number that has prime factors of 2,5 and 7
Just multiply the first three prime numbers together.
1 x 2 x 3 = 6
Two is the smallest prime number and if 10 prime numbers are wanted, and they can repeat, the answer is 210 or 1024.
If by "least number" you mean "smallest positive integer", then the answer is the product of the three smallest primes: 2x3x5 = 30
Just multiply the two smallest prime numbers. That's your number.
There isn't one. Negative numbers have prime factors and numbers don't stop. The smallest positive numbers with a prime factor is 2.
2 and 3 are the smallest prime numbers. So answer is 2^3 * 3^3 = 216
The smallest positive integer is 3.
