How many positive integers less than 1000 are multiples of 5 and equal to 9 times an even integer?
There are eleven such numbers.Get the common multiple of those numbers. All other common multiples will be multiples of this common multiple; that is, you can multiply the common multiple by 1, by 2, by 3, etc. to get additional numbers that are multiples of both numbers.
What pair of numbers have the most common multiples less than 100?
1 and 2
What are all the common multiples of 8 and 9 that are less than 100 and how?
Just 72. It was found by multiplying 8 and 9. --------------------------------------- The common multiples of two numbers are the multiples of their lowest common multiple. LCM(8, 9) = 72 The common multiples of 8 and 9 are 72, 144, 216, ... The only common multiples less than 100 are 72 only.
What is the ratio of the number of positive common multiples less than 100 of the numbers 3 and 5 to the number of positive common multiples less than 100 of the numbers 2 and 7?
The LCM of two consecutive numbers is their product. The LCM of two consecutive multiples of 5 is their product divided by 5. Two consecutive numbers cannot be multiples of 5.
What are four numbers less than 70 that are multiples of both 3 and 5?
Oh, what a happy little question! Let's paint a picture with numbers. The numbers less than 70 that are multiples of both 3 and 5 are 15, 30, 45, and 60. Just like when we add different colors to our canvas, these numbers come together in perfect harmony. Keep up the beautiful work, my friend!
What is less common factor LCF?
The lowest common factor between two numbers is the multiple apart from 1 that the two numbers share which is the lowest. For example: The numbers 36 and 45. Multiples of 36 are {1,2,3,4,6,9,12,24,36} Multiples of 45 are {1,3,5,9,15,45} It is evident that their shared multiples are 1,3,9. But we exclude 1, therefore 3 is the LCM (or LCF)
How do you know when two pairs of numbers will have an LCM that is less than the product of the numbers?
When their GCF is greater than 1. When they have prime factors in common.
What two numbers have the most multiples less than 100?
All nonzero numbers have an infinite amount of multiples.
Common multiples of four and 11 are less than hundred?
44 and 88 are the only common multiples of 4 and 11 that are less than 100
What are pairs of numbers less than 40 that have a greatest common factor of 12?
12 and 24 12 and 36 24 and 36
What is the greatest common factor of the numbers 6 and 8 before 100?
The highest common factor of 6 and 8 is always 2 - it has to be less than or equal to the smaller of the two numbers.If you mean the highest common multiple of 6 and 8 less than 100, then it is 96.All common multiples of 6 and 8 are multiples of their Lowest Common Multiple.The LCM(6, 8) = 24, thus all common multiples of 6 and 8 are multiples of 24.The largest one less than 100 is:100 ÷ 24 = 41/6⇒ highest multiple of 24 less than 100 is 4 x 24 = 96.
What is a number less than 100 and has factor pairs?
All of the composite numbers less than 100 have factor pairs.
