Yes, 123456789 is a multiple of 3.
To find out if it's a multiple of 3, you add the digits. In this case you would add 1+2+3+4+5+6+7+8+9=45. Now you take that 45 and divide by 3. If there is no remainder it is a multiple but if there is a remainder it is not a multiple. So in this case 45/3=15 with no remainder.
