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.
There are no first 5 multiple. Multiple is singular.

The first common multiple of 4, 5, and 10 is their least common multiple (LCM), which is the smallest number that is a multiple of all three numbers. The LCM of 4, 5, and 10 is 20. The next common multiple would be the next multiple of 20, which is 40. The third common multiple would be the next multiple of 20, which is 60.
