Answer» Correct Answer - Option 1 : 125 Concept Used: The total number of factors of any natural number (N) = ap×bq×cr×………, will be Factors = (p + 1)(q + 1)(r + 1)………, Where a,b,c……. are prime numbers and p,q,r….. are natural numbers. Calculation: Now as the given number is (30)4 represents this in the terms of factors. ⇒ (30)4 = (5×6)4 = (5×2×3)4 = 24×34×54 Now apply the above-mentioned formula ⇒ The total number of factors = (4 + 1)(4 + 1)(4 + 1) ⇒ The total number of factors = 5×5×5 = 125 ∴ The total number of factors is 125 |
