2 x 3 x 5 x 7 = 210
2 x 3 x 5 x 7 = 210
210
210
Because the four smallest prime numbers are 2, 3, 5, and 7. If you multiply these four together you get 210 (which makes 210 the smallest number divisible by four unique prime numbers).
The smallest number divisible by first four prime numbers is 2x3x5x7 = 210.
210
They are 210, 330, 390 and 462.
16 if the prime factors don't have to be distinct. 210 if they do.
210 has 4, which is the maximum possible. There are other numbers with 4 different prime factors.
The first four prime numbers are 2, 3, 5, 7. The product of these numbers is 2 x 3 x 5 x 7 = 210
2 x 3 x 4 x 7 = 210
All composite numbers can be expressed as unique products of prime numbers. This is accomplished by dividing the original number and its factors by prime numbers until all the factors are prime. A factor tree can help you visualize this. Example: 210 210 Divide by two. 105,2 Divide by three. 35,3,2 Divide by five. 7,5,3,2 Stop. All the factors are prime. 2 x 3 x 5 x 7 = 210 That's the prime factorization of 210.
