7
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 :)
These are the first 90 multiples of 7:714212835424956637077849198105112119126133140147154161168175182189196203210217224231238245152159266273280287294301308315322329336343350357364371378385392399406413420427434441448455462469476483490497504511518525532539546553560567574581588595602609616623630
