## What is the smallest number by which 392 must be multiplied so that the product is a perfect cube find the cube root of the number so obtained

Therefore, 392 is not a perfect cube. To make its a cube, we need one more **7**. In that case 392 × 7 = 2 × 2 × 2 × 7 × 7 × 7 = 2744 which is a perfect cube. Hence the smallest natural number by which 392 should be multiplied to make a perfect cube is 7.

## What is the smallest number which when multiplied by 392 gives a perfect square

Correct Option: D. Clearly, when 392 is multiplied by **2**, the product is a perfect square.

## Which of the following numbers must be multiplied to 392 to get a perfect cube 2 points 2 3 4 7

We know, a perfect cube has multiples of 3 as powers of prime factors. Here, number of 2's is 3 and number of 7's is 2. So we need to multiply another **7** to the factorization to make 392 a perfect cube. Hence, the smallest number by which 392 must be multiplied to obtain a perfect cube is 7.

## Which of the following numbers must be multiplied to 392 to get a perfect cube class 8

so 2×2×2 makes a cubic pair but 7 is left out so if we multiply 392 by **7×7** … 7 will also form a cubic pair hence 7 is the no.

## What number should be multiplied to 392 to get a perfect cube

To make its a cube, we need one more **7**. In that case 392 × 7 = 2 × 2 × 2 × 7 × 7 × 7 = 2744 which is a perfect cube. Hence the smallest natural number by which 392 should be multiplied to make a perfect cube is 7.

## What should be multiplied to 392 so as to make it a perfect cube

So we need to **multiply another 7** to the factorization to make 392 a perfect cube. Hence, the smallest number by which 392 must be multiplied to obtain a perfect cube is 7.

## Which smallest number 392 must be multiplied so as to make the product a perfect cube

In that case 392 × 7 = 2 × 2 × 2 × 7 × 7 × 7 = 2744 which is a perfect cube. Hence the smallest natural number by which 392 should be multiplied to make a perfect cube is **7**.

## Which smallest natural number 392 must be multiplied so as to make the product a perfect cube A 2 B 14 C 7 D 49

392 x 7 = **2744**. cube root of 2744 = 14 x 14 x 14 = 14. Hope it helps!!!!

## What should be added to 392 to get a perfect square number

Answer: **2** is the smallest number by which 392 should be multiplied. The number obtained is 784 which is the square of 28. By prime factorization we come to know that 2 should be multiplied to make 392 a perfect square.

## What is the smallest positive integer by which 108 can be multiplied to make it a perfect square

3∴ **3** must be multiplied to 108 to make it a perfect square.
