Mark the positions in the above picture with position numbers respectively.

1

2,3

4,5,6

Because the sum of the numbers on the vertices of each small triangle is equal.

Therefore, digit 1 = digit 5, digit 2 = digit 6, digit 3 = digit 4.

1，2，3 = 10。

Can only be 2, 3, 5

So these six numbers are two 2, 3 and 5 respectively.

Product of 6 prime numbers =900
