The prime factors of 7800 are 2, 3, 5 and 13
Well, isn't that a happy little question! To find the smallest number that 7800 must be multiplied by to give a square number, we need to break down 7800 into its prime factors. Once we have those, we can pair them up to form perfect squares. By doing this, we can see that the smallest number 7800 must be multiplied by to give a square number is 3, because when we pair up all the prime factors, we have every factor in pairs except for one factor of 3. And just like that, we've painted a beautiful solution!
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.
