Given numbers are 309,338,417,891
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 309,338,417,891 is 4311679086.
Find LCM of 309,338,417,891 with Prime Factorization
3 | 309, 338, 417, 891 |
103, 338, 139, 297 |
Multiply the prime numbers at the bottom and the left side.
3 x 103 x 338 x 139 x 297 = 4311679086
Therefore, the lowest common multiple of 309,338,417,891 is 4311679086.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
309 x 338 x 417 x 891 = 38805111774
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
309 : 1, 3, 103, 309
338 : 1, 2, 13, 26, 169, 338
417 : 1, 3, 139, 417
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 309,338,417,891, is 1.
Now, the common factors can be found like this.
309:3x 103
338:2x 13x 13
417:3x 139
891:3x 3x 3x 3x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 38805111774/(1x9)
LCM = 38805111774/9
LCM = 4311679086
Thus, we can understand that the LCM of 309,338,417,891 is 4311679086.
