replace 7 with x:
x+2x=3x
x+2x+3x=6x
all ten of them -> 55x
Put the 7 back in:
55(7)=385
OR:
The first ten multiples of 7 are
7,14,21,28,35,42,49,56,63,70
The product of the multiples will then be
7+14+21+28+35+42+49+56+63+70= 385 :)
7 14 21 28 35 42 49 56 63 70
The first 3 multiples of 7 are: 7, 14, and 21.
7, 14, 21, 28, 35, 42, 49, 56, 63, 70
