Question 1

least prime factors are 2,3,5,7 smallest integer is 2 3 5*7=210

Hey yo,

since it is smallest (+) number of 4 different prime factors,

prime numbers(1st 4) = [2,3,5,7],

therefore, smallest (+) integer = 2 x 3 x 5 x 7 = 210,

thanks...

Find out the smallest four different prime numbers .

$\text{P={2,3,5,7,11.....}}$ $\rightarrow$ $\infty$

smallest four different prime numbers are $\text{SP={2,3,5,7}}$

$\text{2×3×5×7 = 210}$

$\therefore{\boxed{210}}$ is the answer.

Note :(SP) is the abriviate form of (Smallest prime numbers)

since it is smallest (+) number of 4 different prime factors, prime numbers(1st 4) = [2,3,5,7], therefore, smallest (+) integer = 2 x 3 x 5 x 7 = 210, thanks...

The smallest four prime numbers are (2,3,5,7) Now multiply them, the product comes out to be 210 which is the answer.

2 * 3 * 5 *7 = 210

We can find answer by multiplying the four smallest prime numbers which are 2,3,5 and 7.Hence,we get 2x3x5x7=210
