The first one is 5x1=5 the next is 5x2=10 The number itself is always the first multiple. This is important because when finding a common multiple, one needs to consider the number itself as a multiple Example: Find the least common multiple of 5 and 10, the answer is 10 since it is a multiple of itself and 5xs2 is 10.
There are no first 5 multiple. Multiple is singular.

The lowest common multiple of 11 and 5 is the smallest natural number of which 11 and 5 are both divisors. The first few multiples of 11 are 11, 22, 33, 44 and 55. The first few multiples of 5 are 5, 10, 15, 20, 25, 30, 35, 40, 45, 50 and 55. The first multiple of either 11 or 5 which is the same for both is 55. Therefore, 55 is the lowest or least common multiple.
The question is a bit ambiguous: "the sum of the product ... " does not seem to make sense. The first 5 digit number is 10000 the first 5 digit multiple of 6 is 10002 Their product is 100020000. I am not sure what to sum, though.
10 itself is a multiple of 5, so any multiple of 10 must also be a multiple of 5.

The first multiple of any number is the number itself.
