18, 36, and 45what is the GCF and LCM
Answer (2)
Answer:the GCF of 18,36 and 45 is 9and the LCM of 18,36,and 45 is 180
Answer:- The Greatest Common Factor is nine/9...- The Least Common Multiple is one hundred eighty/180...Step-by-step explanation: Greatest Common Factor (GCF):1. First, break down each number into its basic building blocks, which are called prime factors. For example, the number eighteen can be broken down into two and three times three. The number thirty-six can be broken down into two times two and three times three. The number forty-five can be broken down into three times three and five.2. Next, look for the prime factors that all three numbers share. In this case, all three numbers share two threes (three times three).3. The Greatest Common Factor is found by multiplying these shared factors together. Since all three numbers share three times three, the GCF is nine. Least Common Multiple (LCM):1. Again, start by breaking down each number into its prime factors. For eighteen, that's two and three times three. For thirty-six, that's two times two and three times three. For forty-five, that's three times three and five.2. To find the Least Common Multiple, you take each prime factor that appears in any of the numbers, but you take it the highest number of times it appears. For example, the factor two appears as two times two in thirty-six, so you take two times two. The factor three appears as three times three in all the numbers, so you take three times three. The factor five only appears in forty-five, so you take one five.3. Multiply all these factors together to get the Least Common Multiple. In this case, that gives you one hundred eighty.Final Answers- The Greatest Common Factor is nine.- The Least Common Multiple is one hundred eighty.
