5 11 35 4511

7 11 7 4511

11 11 1 4511

13 1 1 4511

Bring down any numbers that are not evenly divisible by the prime number.

When the last row of results is all 1's you are done.

Find the product of the prime numbers in the first column to get the LCM:

LCM = 2 x 2 x 3 x 5 x 7 x 11 x 13 x 347

LCM = 20,840,820
