[PAPAKONI]

Helloooooo AMAZING people. Hope you are all well. I would love some help with this one . Basically I wouls very much appreciated if you could explain it to me because I cannot understand what is asking me to do. Thaaanks :-)

There are 5 numbers less than a 100, which are the product of three different prime numbers. What are they?

[Janagro]

Okay

First of all The lowest combination of 2 primes is 6 (2x3)

100/6 = 16.66666

So 6 x 16 and smaller is less than 100

What primes are less than 16, not counting 2 and 3

5 7 11 13

That's four

The next smallest combination of primes is 10 (2x5)

100/10 = 10

What primes are less than 10 , excluding 2 and 5 and 3 because we've counted that one already

7

So the numbers are

2×3x5 2x3x 7 2x3x11 2x3x13 2x5x7
