Correct Answer - Option 1 : 17
Given:
The LCM of two prime numbers is 221 and one number is 13
Formula used:
Product of numbers (a × b) = HCF of (a, b) × LCM of (a, b)
Calculation:
Let the number be x and we know that the HCF of two prime numbers is always one
∴ HCF of number is 1
Now, we know the property that the Product of numbers (a × b) = HCF of (a, b) × LCM of (a, b)
∴ 221 × 1 = 13 × x
⇒ x = 17
Hence, option (1) is correct
