The 5.4L motors are all what are referred to by insiders as Windsor motors. This means they were built at the Windsor engine plant. It also means they come with pressed on cam gears which are not adjustable. So, the first thing you'll have to do is get a set of "Romeo" cams and gears. The cams are the same spec as Windsor cams but they have bolt on cam gears which allow for adjustment in different ways.
To adjust cam timing you can use one of several methods (this should only be attempted by someone with the skills, so we won't get really detailed).
1. Companies like Fidanza offer cam gears for Ford "modular" engines with adjustability built into them. You simply loosen the adjusting screws on them and twist to the timing spec indicated on the timing marks built into them.
2. You can grind and weld up the keyway on the stock cam gear. This is sadistically difficult and precise. Don't do it.
3. You can really foul the motor by advancing or retarding the whole works on both sides by 1 tooth/link. There is no practical application of this as it usually represents a failure to correctly assemble the timing gear in the first place.
Here is the single best write-up, with many pictures of the general how-to for modular engines. While it focuses on 4.6L motor the procedure for 5.4L engines is identical.
99 x 54 = 5346
The GCF is 9.
The greatest common factor of 99 and 54 is 9.
54/99 = 6/11
Greatest Common Divisor (GCD) for 54 99 is 9.
Your question does not make since.
45+54=99 99*2=198 198 is the answer.
The GCF of 36, 54, and 99 is 9.
54 + 45 = 99
45 + 54 = 99
54 and 99 are not prime numbers because they have more than two factors.
