5 3
Step 1.Find the LCD of 5 and 3
To find the LCD (Least Common Denominator) of 5 and 3, you need to identify the smallest number that is divisible by both 5 and 3.
Step 2: Prime factorize the numbers
The prime factorization of 5 is simply 5 (as 5 is a prime number).
The prime factorization of 3 is also 3 (as 3 is also a prime number).
Step 3: Find the LCD
To find the LCD, you need to choose the highest power of all the prime factors involved. In this case, the prime factors are 3 and 5.
Since both numbers only have one prime factor each and there are no repeated prime factors, the LCD is simply the product of the two numbers: 5 * 3 = 15.
Therefore, the LCD of 5 and 3 is 15.
