lcm(2, 7) = 14 → first 3 common multiples are: 14, 28, 42; lcm(2, 8) = 8 → first 3 common multiples are: 8, 16, 24; lcm(7, 8) = 56 → first 3 common multiples are: 56, 112, 168; lcm(2, 7, 8) = 56 → first 3 common multiples are: 56, 112, 168.
1, 2, 3, 4, 5, 6, 7, 8, 9 and 10
The first 6 multiples of 7 are: 7, 14, 21, 28, 35, and 42.
7
7, 14, 21, 28
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 :)
