1080 = 2^3x3^3x5 200= 2^3x5^2 LCM (1080,200) = 2^3x3^3x5^2 = 1800
15 x 2 = 30
2+3*5 = 2 + 15 = 17
30
Multiply the factors, and you will know.

There are 15 cells in a 3x5 table, calculated by multiplying the number of rows (3) by the number of columns (5).
(2x3)+(3x5)-(3x2)= 2x3=6 3x5=15 3x2=6 So..... 6x25-6= 6x25=150 150+6=156
Here is one factor tree of 300: 300 20 x 15 (4x5) x (3x5) ((2x2)x5) x (3x5) You have reduced it to prime numbers, so you are finished. The factors of 300 are 2, 2, 3, 5, and 5.
