Physics Lab -- greatest common factor between all these numbers 1. The problem statement, all variables and given/known data Hey, how can I find the greatest common factor between all these numbers? Please reply as soon as possible, it is an assignment due tomorrow. 27.69 3.15 0.59 4.71 18.08 22.84 31.08 19.11 21.91 9.7 38.78 42.82 38.89 5.85 2. Relevant equations No equations used. 3. The attempt at a solution My attempt was that I entered all these value on excel, I converted all these numbers to whole numbers. I used =gcf on a cell, and in brackets I put all that data. It gives me a common factor of 1, apparently that answer is wrong, my teacher even said. I need the common factor in decimal form. I even converted it back to decimal form, which is 0.01, and that answer is also wrong. Gow can I get the common factor in decimal form?
