The greatest common factor (GCF) is often also called the greatest common divisor (GCD) or highest common factor (HCF). Keep in mind that these different terms all refer to the same thing: the largest integer which evenly divides two or more numbers.
The greatest common factor of 1470, 2688, and 4032 is 42

The first 20 multiples of 192: 192, 384, 576, 768, 960, 1152, 1344, 1536, 1728, 1920, 2112, 2304, 2496, 2688, 2880, 3072, 3264, 3456, 3648, 3840 . . .
Yes, 120 is divisible by 3. A good rule of thumb for the multiples of 3 is to add up the digits in the number. If the number that comes out is divisible by 3, then it is a multiple of 3. For example, in 120, 1 + 2 + 0 = 3. Therefore, the number is divisible by 3. The process can be repeated for larger numbers. For example, 2688 is divisible by 3 because 2 + 6 + 8 + 8 = 24, and 2 + 4 = 6.

2688.888... = 2688 8/9 = (9*2688 + 8)/9 = 24200/9
My all-time favorite unit of speed, the FF! For reference, a snail typically travels at about 6 FF or 1mm/sec. This converts out to be about a top speed of 3/8 of a mile per week. Conversion factor is 2688 FF = 1mph 185000 / 2688 = 68.82mph ■
