Answer:
We can find the LCM (Least Common Multiple) of these numbers by finding the prime factorization of each number and then multiplying the highest power of each prime factor together.
Prime factorization of 2: 2
Prime factorization of 4: 2^2
Prime factorization of 6: 2 * 3
Prime factorization of 9: 3^2
Prime factorization of 10: 2 * 5
The highest power of 2 is 2^2.
The highest power of 3 is 3^2.
The highest power of 5 is 5^1.
Multiplying these numbers together gives us:
2^2 * 3^2 * 5^1 = 180
Therefore, the LCM of 2, 4, 6, 9, and 10 is 180.
