Given numbers are 646,726,289,315
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 646,726,289,315 is 418578930.
Find LCM of 646,726,289,315 with Prime Factorization
2 | 646, 726, 289, 315 |
3 | 323, 363, 289, 315 |
17 | 323, 121, 289, 105 |
19, 121, 17, 105 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 19 x 121 x 17 x 105 = 418578930
Therefore, the lowest common multiple of 646,726,289,315 is 418578930.
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.
646 x 726 x 289 x 315 = 42695050860
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
289 : 1, 17, 289
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,726,289,315, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
726:2x 3x 11x 11
289:17x 17
315:3x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 17 = 102
Therefore, the value for common factors is 102.
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 = 42695050860/(1x102)
LCM = 42695050860/102
LCM = 418578930
Thus, we can understand that the LCM of 646,726,289,315 is 418578930.
