Suppose p, q, r and s are four prime numbers, each one a 100 (or more) digits long.Let A = p*q and B = r*s then finding the LCM of A and B is extremely complex - even with computers. Data encryption is based on such numbers.
By finding multiples for each number. Example: 10 & 15 10-1,2,5,10 15-1,3,5,15 It would be 5 because it's the lowest common multiple(LCM)
There is no "most common multiple". To find all common multiples, you start by finding the least common multiple. All other common multiples are multiples of this least common multiple.
By finding the lowest common multiple of the denominators
No.
Prime factor tree!
The first one is 5x1=5 the next is 5x2=10 The number itself is always the first multiple. This is important because when finding a common multiple, one needs to consider the number itself as a multiple Example: Find the least common multiple of 5 and 10, the answer is 10 since it is a multiple of itself and 5xs2 is 10.
to find the least common multiple of two numbers you must list the factors then you can find out their least common multiple of the two numbers
Common denominators are created by finding the common multiples of unlike denominators.
Lowest Common Multiple-the smallest number that is a multiple of all the numbers in a given set; same as least common multiple. Example-for 6,9, and 18, 18 is the lowest common multiple. =]its lowest common multiple
To find a common multiple - you need to have something to compare it to ! For example, the least common multiple of 2 & 3 is 6 !
In general, the two are not related.
By finding their lowest common denominator by means of their lowest common multiple
