Given numbers are 814,698,647,957
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 814,698,647,957 is 15990916854.
Find LCM of 814,698,647,957 with Prime Factorization
| 2 | 814, 698, 647, 957 |
| 11 | 407, 349, 647, 957 |
| 37, 349, 647, 87 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 37 x 349 x 647 x 87 = 15990916854
Therefore, the lowest common multiple of 814,698,647,957 is 15990916854.
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.
814 x 698 x 647 x 957 = 351800170788
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.
814 : 1, 2, 11, 22, 37, 74, 407, 814
698 : 1, 2, 349, 698
647 : 1, 647
957 : 1, 3, 11, 29, 33, 87, 319, 957
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 814,698,647,957, is 1.
Now, the common factors can be found like this.
814:2x 11x 37
698:2x 349
647:647
957:3x 11x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11 = 22
Therefore, the value for common factors is 22.
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 = 351800170788/(1x22)
LCM = 351800170788/22
LCM = 15990916854
Thus, we can understand that the LCM of 814,698,647,957 is 15990916854.
