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).
2 and 3 are the smallest prime numbers. So answer is 2^3 * 3^3 = 216
There isn't one. Negative numbers have prime factors and numbers don't stop. The smallest positive numbers with a prime factor is 2.
what is the smallest positive integer that has four different prime factors
Just multiply the first three prime numbers together.
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.
The smallest prime factors are 2,3,5,7 thus the smallest number would be the product of these will be 210
Multiply the 4 smallest prime numbers... 2 X 3 X 5 X 7 = 210
All prime numbers only have one prime factor.
Two is the smallest prime number and if 10 prime numbers are wanted, and they can repeat, the answer is 210 or 1024.
Just multiply the first five prime numbers! 2x3x5x7x11 = 6x35x11 = 210x11 = 2310. Any multiple of this number "has the first five prime numbers as factors", but 2310 is the smallest such number.
2 is the smallest prime number. Numbers can't have factors larger than themselves. Zero and one aren't large enough to have prime factors.
The smallest prime numbers, after 2, are 3 and 5. 3 x 5 = 15.
154, 308, 462
All numbers have factors. Some factors are prime numbers, some are composite numbers, one is neither. When finding the factors of a number, you find all the factors. The prime factorization is a multiplication string of just prime factors that will total the given number.
2310 has all of those as factors.
Since there are an infinite number of prime numbers, there are infinite numbers with any given number of prime factors.
As a product of its prime factors: 2*3*5*7 = 210
There are several ways to achieve this. For example, any two prime numbers. Or just multiply different small prime factors for each of the numbers - picking different prime factors for each - for example, a power of 2, and a power of 3.
2 222 223
2 x 3 x 5 = 30
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
