A gardener wants to plant trees in his garden in such a way that the number of trees in each row should be the same. If there are 7 rows or 6 rows or 3 rows, then no tree will be leftover. What is the least number of trees required? Correct Answer 42

Concept:

LCM of (1, 2, 3) is 6.

Calculation:

⇒ LCM (7, 6, 3) = 42

⇒ The least number of tree required = 42

∴ The required result will be 42.

Use the rule from left to right for each row and find the answer to the question. Rule: 1. If an even number is followed by an even number, then the first number will be subtracted from the second. 2. If an odd number is followed by an odd number, then both will be added. 3. If an odd number is followed by an even number, then the even number will be subtracted from the square of the odd number. 4. If an even number is followed by an odd number, then the odd number will be subtracted from the even number.
