The LCM of 616,694,391,836,811 is 1287838486088.
Find LCM of 616,694,391,836,811 with Prime Factorization
| 2 | 616, 694, 391, 836, 811 |
| 2 | 308, 347, 391, 418, 811 |
| 11 | 154, 347, 391, 209, 811 |
| 14, 347, 391, 19, 811 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 14 x 347 x 391 x 19 x 811 = 1287838486088
Therefore, the lowest common multiple of 616,694,391,836,811 is 1287838486088.
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.
616 x 694 x 391 x 836 x 811 = 113329786775744
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.
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
694 : 1, 2, 347, 694
391 : 1, 17, 23, 391
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
811 : 1, 811
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 616,694,391,836,811, is 1.
Now, the common factors can be found like this.
616:2x 2x 2x 7x 11
694:2x 347
391:17x 23
836:2x 2x 11x 19
811:811
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 11 = 88
Therefore, the value for common factors is 88.
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 = 113329786775744/(1x88)
LCM = 113329786775744/88
LCM = 1287838486088
Thus, we can understand that the LCM of 616,694,391,836,811 is 1287838486088.
