The least natural number that is divisible by three different prime numbers can be calculated by multiplying the smallest three prime numbers. The three smallest primes are:
- 2
- 3
- 5
To find the least natural number:
Least number = 2 × 3 × 5
Now let’s do the multiplication:
First, multiply 2 and 3:
2 × 3 = 6
Then multiply the result by 5:
6 × 5 = 30
Thus, the least natural number that is divisible by three different primes is 30.
In summary, by using the smallest primes (2, 3, and 5), their product gives us the least natural number that meets the criteria of being divisible by three different primes.
