The prime factors of 7800 are 2, 3, 5 and 13
Oh, dude, let me break it down for you. So, 7800 is 2^3 * 3 * 5^2 * 13. To make it a square number, each prime factor needs to appear an even number of times. So, the smallest number it must be multiplied by is 2 * 5 * 13, which is 130. Easy peasy lemon squeezy!
To find the Least Common Multiple (LCM) of two numbers, you first need to find the prime factorization of each number. The prime factorization of 2700 is 2^2 * 3^3 * 5^2 and the prime factorization of 7800 is 2^3 * 3 * 5^2. Then, you take the highest power of each prime factor that appears in either number. In this case, the LCM of 2700 and 7800 is 2^3 * 3^3 * 5^2, which equals 10800.
Prime factors are factors that are also prime numbers.
