Given numbers are 681,375,912,387,819
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 681,375,912,387,819 is 303781842000.
Find LCM of 681,375,912,387,819 with Prime Factorization
| 3 | 681, 375, 912, 387, 819 |
| 3 | 227, 125, 304, 129, 273 |
| 227, 125, 304, 43, 91 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 227 x 125 x 304 x 43 x 91 = 303781842000
Therefore, the lowest common multiple of 681,375,912,387,819 is 303781842000.
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.
681 x 375 x 912 x 387 x 819 = 73818987606000
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.
681 : 1, 3, 227, 681
375 : 1, 3, 5, 15, 25, 75, 125, 375
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
387 : 1, 3, 9, 43, 129, 387
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,375,912,387,819, is 3.
Now, the common factors can be found like this.
681:3x 227
375:3x 5x 5x 5
912:2x 2x 2x 2x 3x 19
387:3x 3x 43
819:3x 3x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3 = 81
Therefore, the value for common factors is 81.
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 = 73818987606000/(3x81)
LCM = 73818987606000/243
LCM = 303781842000
Thus, we can understand that the LCM of 681,375,912,387,819 is 303781842000.
