Mga Hakbang ng Solution

I-factor ang mga expression na hindi pa na-factor.

$$18=2\times 3^{2} 16=2^{4} 20=2^{2}\times 5 18=2\times 3^{2} 28=2^{2}\times 7 18=2\times 3^{2} 10=2\times 5 33=3\times 11 12=2^{2}\times 3 33=3\times 11 12=2^{2}\times 3 12=2^{2}\times 3 10=2\times 5 22=2\times 11 40=2^{3}\times 5 45=3^{2}\times 5 30=2\times 3\times 5 16=2^{4} 35=5\times 7$$

Tukuyin ang lahat ng factor at ang highest power ng mga ito sa lahat ng expression. I-multiply ang mga highest power ng mga factor na ito para makuha ang least common multiple.

$$1540012320ABCD$$
