Question

find the least number by which 1323 must be multiplied so that product is a perfect cube​

Answer 1

Answer:

Step-by-step explanation:

On dividing 1323 by 3 and 7 we get 3 x 3 x 3 x 7 x 7. This shows that a 7 is required to make this number a perfect cube. So, there is short of a '7' to form a trio. Hence, 1323 must be multiplied by 7, so that the product is a perfect cube.

Answer 2

Answer:

7 is the least number by which 1323 must be multiplied so that the product is a perfect cube

Step-by-step explanation:

firstly we need to take LCM of 1323,

it results as,

1323=3×3×3×7×7

here,

if we simply multiply 1323 with 7

then we get resultant number = 9261

which is a perfect cube of 21(3×7)

so, 7 is the least number by which 1323 must be multiplied so that the product is a perfect cube
