$L C M = 91 b^{3}$ $color(magenta)(L C M = 91 b^3$

To find L C M of $13 b^{3}, 7 b^{2}$ $13b^3, 7b^2$

$Factors of 13 b^{3} = 13 \cdot b \cdot b \cdot b$ $"Factors of " 13 b^3 = 13 * color(red)(b * b) * b$

$Factors of 7 b^{2} = 7 \cdot b \cdot b$ $"Factors of " 7 b^2 = 7 * color(red)(b * b)$

$:. L C M = 13 * color(red)( b * b) * b * 7 = 91b^3$
