Multiples of 5: 5, 10, 15, 20, 25, 30, 35
Multiples of 6: 6, 12, 18, 24, 30, 36
The first common multiple is 30.
You can work out other answers by multiplying 30 to any number.
For example: 30*4=120
120 can be divided by 6 and 5.
The smallest answer will be 30 because there is no other number, that is in the 30 times tables, that is smaller than 30.
