let the 4 numbers be

x, x+1, x+2, x+3 , where x is an integer.

x + x+1 + x+2 + x+3

= 4x + 6

= 2(x+3)

Any integer multiplied by 2 must be even

or

If any integer has a factor of 2, it must be even by definition.

The gcf(a,b) = 495 and lcm( a,b) =31,185 Find possible values of a and b if a is divisible by 35 and b is divisible by 81.

Kendra,

piggy-backing on other students' questions has two disadvantages:

1. Tutors do not get to see your post (as in the present case)

2. it slows down the other student's getting a response.
