Solution: The GCF of 45 and 50 is 5.
The factors of 45 are 1, 3, 5, 9, 15, and 45. Hence, the common factors of 45 and 90 are 1, 3, 5, 9, 15, and 45.
If the LCM of 50 and 45 is 450, Find its GCF.
Therefore, the greatest common factor = 2250/450 = 5.
The factors of 50 are 1, 2, 5, 10, 25, 50. The factors of 120 are 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120. The common factors of 20, 50 and 120 are 1, 2, 5 and 10.
The factors of 50 are 1, 2, 5, 10, 25 and 50.
LCM of 45 and 50 is 450. The least common multiple of any two or more natural numbers is the number that is the lowest of their common multiples.
All the factors of 45 are 1, 3, 5, 9, 15, and 45.
As per the LCM method, we can obtain the GCD of any two numbers by finding the product of both the numbers and the least common multiple of both the numbers. The formula which is used to find the GCD is as follows: GCD (a, b) = (a × b)/ LCM (a, b).
Solution: The GCF of 48 and 50 is 2.
LCM of 45 and 60 is 180. The value divisible evenly by 45 and 60 gives the LCM value. Least common multiples of 45 and 60 can be found from the multiples which are common. (45, 90, 135, 180, 225, 270, ….)
Once you do find a match, or several matches, the smallest of these matches would be the Least Common Multiple. For instance, the first matching multiple(s) of 45 and 52 are 2340, 4680, 7020. Because 2340 is the smallest, it is the least common multiple. The LCM of 45 and 52 is 2340.
Solution: The GCF of 50 and 46 is 2.
The factors of 45 and 50 are 1, 3, 5, 9, 15, 45 and 1, 2, 5, 10, 25, 50 respectively.
The GCF of 54 and 45 is 9. To calculate the GCF of 54 and 45, we need to factor each number (factors of 54 = 1, 2, 3, 6, 9, 18, 27, 54; factors of 45 = 1, 3, 5, 9, 15, 45) and choose the greatest factor that exactly divides both 54 and 45, i.e., 9.
The greatest common divisor (GCD) of two or more numbers is the greatest common factor number that divides them, exactly. It is also called the highest common factor (HCF).
The least common multiple (LCM) of two integers is the smallest positive integer that is a multiple of both. The greatest common divisor (GCD) of two integers is the largest positive integer dividing both.
Solution: The GCF of 50 and 24 is 2.
In arithmetic: Fundamental theory. …of these numbers, called their greatest common divisor (GCD). If the GCD = 1, the numbers are said to be relatively prime. There also exists a smallest positive integer that is a multiple of each of the numbers, called their least common multiple (LCM).
Solution: The GCF of 45 and 56 is 1.
3 is a prime number because 3 can be divided by only two number's i.e. 1 and 3 itself. In the same way, 2, 5, 7, 11, 13, 17 are prime numbers.
Prime numbers need to have exactly two factors. Why is 2 a prime number? 2 is a prime number because its only factors are 1 and itself.
What is an integer and what are examples of integers? An integer (pronounced IN-tuh-jer) is a whole number (not a fractional number) that can be positive, negative, or zero. Examples of integers are: -5, 1, 5, 8, 97, and 3,043. Examples of numbers that are not integers are: -1.43, 1 3/4, 3.14, .09, and 5,643.1.
