What is the least common multiple of 45 and two?
The LCM of 2 and 45 is 90.
How is LCM calculated?
One way to find the least common multiple of two numbers is to first list the prime factors of each number. Then multiply each factor the greatest number of times it occurs in either number. If the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.
Which of the following is the GCF and LCM of 30 45 and 60?
Answer: LCM of 30, 45, and 60 is 180. Explanation: The LCM of three non-zero integers, a(30), b(45), and c(60), is the smallest positive integer m(180) that is divisible by a(30), b(45), and c(60) without any remainder.
What is the common factor of 45 and 27?
9
There are 3 common factors of 27 and 45, that are 1, 3, and 9. Therefore, the greatest common factor of 27 and 45 is 9.
What is the GCF of 30 and 45 1 point?
The GCF of 30 and 45 is 15. To calculate the greatest common factor of 30 and 45, we need to factor each number (factors of 30 = 1, 2, 3, 5, 6, 10, 15, 30; factors of 45 = 1, 3, 5, 9, 15, 45) and choose the greatest factor that exactly divides both 30 and 45, i.e., 15.What is the multiples of 45?

What is the GCF of 12 and 120?
The GCF of 12 and 120 is 12.
How do you find the greatest common factor?
Here’s how to find the GCF of a set of numbers using prime factorization:
- List the prime factors of each number.
- Circle every common prime factor — that is, every prime factor that’s a factor of every number in the set.
- Multiply all the circled numbers. The result is the GCF.
