Correct Answer - Option 2 : 60
The given number is:
213 × 35 × 53 × 76
For each term, the perfect cubes can be obtained as:
For 213 = 20, 23, 26, 29, 212; i.e. 5 terms
For 35 = 30, 33; i.e. 2 terms
For 53 = 50, 53; i.e. 2 terms
For 76 = 70, 73, 76; i.e. 3 terms
So, we have the multiples of the number 213 × 35 × 53 × 76 as perfect cubes = 5 × 2 × 2 × 3 = 60
∴ The number of multiples of the number 213 × 35 × 53 × 76 are perfect cubes or complete cubes, are 60
