Answer 2

Answer:

Multiples of 56 are obtained by multiplying 56 with counting numbers.

Hence multiples of 56 are infinite. The first 5 numbers in the multiplication table of 56 are 56, 112, 168, 224, and 280. We can calculate multiples of 56 by skip counting also, as shown below.

The first ten multiples of 56 are 56, 112, 168, 224, 280, 336, 392, 448, 504, and 560.

Adding the multiples, 56 + 112 + 168 + 224 + 280 + 336 + 392 + 448 + 504 + 560 = 3080. Thus, the sum is 3080.
