What is the LCM of 800?
You can't do the LCM of 400 because you need two numbers to do the LCM of, for example, the LCM of 12 and 8 would be 24.
What is the LCM of 960 and 1600?
The LCM of 960, 1600 is 4800.
What is the LCM for 5 and 8 and 17?
The LCM of these numbers is 340. LCM is Least Common Multiple.
What is the least common multiple of 16 and 20?
The LCM of 16 and 20 is 80.The LCM is the product of the numbers divided by their GCF.The GCF of 16 and 20 is 4. (We know the GCF can't be any larger than the difference between the two numbers. Trying 4 divided into 16 and 20 shows that it is a factor of both).16 * 20 / 4 = 80, which is the LCM.The LCM is: 80Method of prime factorization: Expressing each number as the product of prime numbers.20 = 2x2x516 = 2x2x2x2H.C.F. of 20 and 16 = 2x2 = 4.L.C.M.(20,16) = H.C.F.(20,16) x Product of uncommon numbers in prime factorizationsL.C.M.(20,16) = 4 x 5x2x2 = 4x20 = 80.Alternate method:Multiples of 20 are 20, 40, 60, 80, 100, 120, 140, 160, 180,...Multiples of 16 are 16, 32, 48, 64, 80, 96, 112, 128, 144, 160,...As we can see that there exists infinite common multiples but the least common multiple is 80.
What is the next common multiple after LCM of 5 and 8?
Common multiples of a set of numbers are the multiples of their LCM. The next common multiple is the second multiple of LCM of 5 and 8. LCM of 5 and 8 is 40 and the second multiple of 40 is 80. So, the next common multiple is 80.
