Well, honey, if the ones digit of a number is 0, then that number must have 2 and 5 as factors. Why? Because any number ending in 0 is a multiple of 10, which is made up of 2 and 5. So, to answer your question, the number must have both 2 and 5 as factors.
Not necessarily, but at least ''one'' of them must be even, unless the two numbers are both the (irrational) square root of the same even number.
an exact decimal must be with the number 0. in it or it is not exact.
The GCF of 8 and 343 is 1. Since there is no common prime factor, you must look for a number that will divide into both 8 and 343. This number is 1. Therefore, the greatest common factor is 1
Add 7 to 5,621, to get 5,628. That's (469 x 12).
