The $\text{g.c.d.}$ (greatest common divisor) of any two consecutive natural numbers is:

$A$ sweet seller has $420$ Kaju burfis and $130$ Badam burfis. He wants to stack them in such a way that each stack carries the same number of items and they take up the least area of the tray. What is the maximum number of burfis that can be placed in each stack for this purpose?

If $\text{g.c.d.}(336, 52) = 4$,then $\text{l.c.m.}(336, 52) = \dots$

The smallest positive number divisible by every integer from $2$ to $10$ is:

If the Least Common Multiple $(LCM)$ of two numbers is equal to their product,then their Greatest Common Divisor $(GCD)$ is . . . . . . .

If $HCF(306, 657) = 9$,find $LCM(306, 657)$.
