What is the least common multiple of each factor pair 6 and 7?
The Least Common Multiple (LCM) for 6 7 is 42.
What is the difference between greatest common factor and least common factor?
The greatest common factor of two (or more) integers is the biggest whole number that divides into each one of them. The least common factor is the smallest whole number that divides into each one of them and must be 1. Very possibly, you meant the least common multiple, however?
What is the least common multiple of 9 36 and 45?
The least common multiple is the smallest integer of which each number is a factor. The LCM of 9, 36, and 45 is 180.
What is the least common multiple other than 0 common to sets of multiples?
The least common multiple (LCM) of two or more numbers is the smallest number that is a multiple of each of the numbers in the set. For sets of multiples, the LCM is the smallest number that is a multiple of all the numbers in the sets. The LCM can be calculated by finding the prime factorization of each number and then taking the highest power of each prime factor that appears in any of the numbers.
Why is the least common factor not something of mathematical interest?
You do not find the greatest common multiple because there is really no such thing. Once you find the least common multiple of a set of numbers, you can keep adding the LCM to itself over and over again. Each new number you get will be a common multiple of your set of numbers, but each new number will always be larger than the previous. This means that you can keep adding while the number approaches infinity and you will still never find a greatest multiple.
What is the least common multiple of 13 and 117?
Since 13 is a factor of 117, the least common multiple is 117. 13 x 9 = 117 117 x 1 = 117 Another way to determine the least common multiple is to multiply both numbers and divide by their greatest common factor. The greatest common factor of 13 and 117 is 13, so the least common multiple is 13 x 117 ÷ 13 = 117. Another way to determine the least common multiple is to determine the prime factors of the numbers and take the highest power of each prime factor. The prime factors of 13 are 13. The prime factors of 117 are 32 and 13. The highest power of 3 is 32 and the highest power of 13 is 131. Therefore, the least common multiple of 13 and 117 is 32 x 131 = 9 x 13 = 117.
What is the least common factor of 16 20 and 24?
There is really no such thing as a "greatest common multiple". Once you find the least common multiple of a set of numbers, you can keep adding the LCM to itself over and over again. Each new number you get will be a common multiple of your set of numbers, but each new number will always be larger than the previous. This means that you can keep adding while the number approaches infinity and you will still never find a greatest multiple.
What is is the least common multiple of 12 and 21?
The LCM of 12 and 21 is 84. To find the LCM, prime factor both numbers then multiply each factor the most times it was used in either number.12=2x2x321=3x7lcm=2x2x3x7=84The Least Common Multiple (LCM) for 12 21 is 84.
Does a factor mean the same as a highest common multiple?
No.When talking about factors and multiples the numbers are integers (whole numbers).A factor of a number means that the number is a multiple of the factor; the factor divides into the number without any remainder.There is no such thing as a Highest Common Multiple - it is always possible to find a higher common multiple (by adding the Lowest Common Multiple to the supposed highest common multiple).There is a Lowest Common Multiple (LCM) which is the smallest number which is a multiple of two or more numbers. It is also called the Least Common Multiple, or when working with fractions it can be referred to as the Least Common Denominator as the two or more numbers are the denominators of the fractions and equivalent fractions are being sought to be able to do an addition or subtraction.There is a Highest Common Factor (HCF) which is the largest number which divides into each of the two or more numbers without remainder. It is also called the Greatest Common Factor. If the numbers are relatively prime (or co-prime) their HCF is 1.
How do you find the least common denominator of a set of unlike fractions?
To find the least common denominator of a set of unlike fractions, you first need to list the prime factors of each denominator. Then, identify the highest power of each prime factor that appears in any of the denominators. Finally, multiply these highest powers together to find the least common multiple, which will be the least common denominator for the fractions.
What is the least common multiple of 4 6 and 24?
Factor each one and multiply the prime factors the times it was used the most in any of the numbers. 6=2x3 9=3x3 25=5x5 2x3x3x5x5=450
How you know that any numbers have at least one common factor?
You can start by listing out each number's factors. Then, when you find at least one common factor, that is your answer!
