Luci cuts a board that is 3/4 yard long into pieces that are
3/8. The pieces she cut can be solve by dividing the board by length of the new
board. The length of the ¾ yards long divided by the desired length of 3/8
yards which is equal to 2 pieces.

LCM = 5 × 3 × 3 × 7 × 2 × 2 × 5
LCM = 6300
<u>Hence, the LCM of 315 , 420 , 525 is 6300</u>
