Growing Garlic

Ben is in the veggie patch with his Mum. They would like to grow some garlic and are deciding how to plant the garlic cloves.

Ben arranges the cloves into three rows and finds that he has one spare clove. How many cloves might he have had to start with?

Ben plants cloves of garlic in two rows and has one clove left over. So he tries again.

• He plants cloves in three rows and has one left over. So he tries again.
• He plants cloves in four rows and has one left over. So he tries again.
• He plants cloves in five rows and has one left over. So he tries again.
• He plants cloves in six rows and has one left over.

We know that he has fewer than 100 garlic cloves. How many did he have?

You could think about how many cloves he might have had if there were more than 100.

#### Solution

Less than 100:
The Number of garlic cloves equals the Lowest Common Multiple of 2, 3, 4, 5, 6 and then plus 1.
LCM = 60 So the Number is 60 + 1 = 61

The first one more than 100:
The numbers of garlic cloves equals 60 x 2 + 1 = 121
