18m³n³r²
72m²n⁴r³ answer​

Answer 1

Question :

Find LCM of $18 {m}^{3} {n}^{2} {r}^{2} \:$and $72 {m}^{2} {n}^{4} {r}^{2}$

Solution :

Split the terms ,

$18 {m}^{3} {n}^{2} {r}^{2}$ :

$= 2 \times 9 \times m \times m \times m \times n \times n \times r \times r$

$72 {m}^{2} {n}^{4} {r}^{2}$ :

$= 2 \times 2 \times 2 \times 9 \times m \times m \times n \times n \times n \times n \times r \times r$

LCM = $2 \times 2 \times 2 \times 9 \times m \times m \times n \times n \times n \times n \times r \times r$

$= 72 {m}^{3} {n}^{4} {r}^{2}$
