My answer is: LCM IS 20
Your answer is right
To find the LCM (Least Common Multiple) of two numbers, such as 4 and 20, you can use the following steps:
1. List the prime factors of each number:
- Prime factors of 4: 2^2
- Prime factors of 20: 2^2 * 5
2. Identify the highest power of each unique prime factor:
- The highest power of 2 is 2^2.
- The highest power of 5 is 5^1.
3. Multiply the highest powers together:
- 2^2 * 5^1 = 4 * 5 = 20
Therefore, the LCM of 4 and 20 is 20. Your answer is correct!
