The LCM is always equal to or greater than(=>) the greatest coefficient.

In this case, the greatest coefficient

is 35. 35 will work only if it is

divisible by all of the other coefficients. 35 is not divisible by 10. Therefore, it does not meet both

requirements. So we try 2*35(70). It meets both requirements. If 70 had not

met both requirements, we would have

tried 3*35 and so on.
