The expression (2 \times 3 \times 5) equals (30). To break it down, first multiply (2) by (3) to get (6), and then multiply (6) by (5) to arrive at the final result of (30).
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.
