Factoring each number into product of primes: 78 = 2 x 3 x 13
104 = 2 x 2 x 2 x 13 While the number 2 is a factor for both numbers, it occurrs three times for 104; Therefore, inlude 2 x 2 x 2 in answer The number 3, which is only common to 78, should be included in answer The number 13, which occurs once for each number should be included in answer Therefore, LCM(78,104) = 2 x 2 x 2 x 3 x 13 = 312

What is the least common multiple of 78?
There is not a least common multiple of a single number, such as 78, because there cannot be a least common multiple without two or more numbers to compare. Common multiples are multiples that the numbers being compared have in common. The least common multiple is the smallest multiple that all the numbers being compared have in common. Examples: The least common multiple of 18 and 78 is 234. The least common multiple of 52 and 78 is 156. The least common multiple of 78 and 195 is 390.
What is the least common multiple of 28 and 78?
The Least Common Multiple (LCM) for 28 78 is 1,092.
What is the GCM and LCM of 78 and 104?
The greatest common factor of the numbers 78 and 104 is 26. The least common multiple of the numbers 78 and 104 is 312.26 and 312, respectively.
What is the least common multiple of 2 26 and 39?
Least common multiple of 2 26 and 39 is 78.
What is the least common multiple 78 90 and 140?
The least common multiple (LCM) refers to a multiple that is COMMON to two or more numbers. You have only one number in the question! The least multiple of a number is itself.
