99.30.28.46.54 how to decompose the mass factor

99=3x3x11 30=2x3x5 28=2x2x7 46=2x23 54=2x3x3x3

The divisor of 28 is () and the prime factor of 22 is ()

The divisor of 28 is (1,2,4,7,14,28). The prime factor of 22 is (22 = 2 * 11)

The quality factor should be 210 = (2 × 3 × 5 × 7 × 1) ()

×
In general, the prime factor does not need to be multiplied by one
It's wrong
Positive 210 = 2 × 3 × 5 × 7
