Example: Find the GCF (18, 27) 27 - 18 = 9 18 - 9 - 9 = 0 So, the greatest common factor of 18 and 27 is 9, the smallest result we had before we reached 0. Example: Find the GCF (20,50,120) Note that the GCF (x,y,z) = GCF (GCF (x,y),z).
Sometimes referred to as a buzz saw or by the popular brand name of Skilsaw, circular saws use a toothed blade, typically between 7-Â¼ and 9 inches in diameter. They are the most common type of powered saw, and accept blades that cut all types of wood, metal, plastic, masonry, and more.
Unlike a table saw and a miter saw,which can perform the same functions, a circular saw, sometimes just called a âcirc saw,â is portable. Typical use for a circular saw. Probably the most common use for a circ saw on construction sites is cuttinga 2 by 4 or 2 by 6 to length. You need to cut a piece thatâs 14-1/2 inches long from a piece thatâs maybe 20inches long, so you make a mark on the wood at 14-1/2 inches and set your saw in position so it will cut there.
