Given numbers are 814,789,234,638,856
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 814,789,234,638,856 is 310890736728.
Find LCM of 814,789,234,638,856 with Prime Factorization
| 2 | 814, 789, 234, 638, 856 |
| 3 | 407, 789, 117, 319, 428 |
| 11 | 407, 263, 39, 319, 428 |
| 37, 263, 39, 29, 428 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 37 x 263 x 39 x 29 x 428 = 310890736728
Therefore, the lowest common multiple of 814,789,234,638,856 is 310890736728.
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 789 x 234 x 638 x 856 = 82075154496192
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
789 : 1, 3, 263, 789
234 : 1, 2, 3, 6, 9, 13, 18, 26, 39, 78, 117, 234
638 : 1, 2, 11, 22, 29, 58, 319, 638
856 : 1, 2, 4, 8, 107, 214, 428, 856
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 814,789,234,638,856, is 1.
Now, the common factors can be found like this.
814:2x 11x 37
789:3x 263
234:2x 3x 3x 13
638:2x 11x 29
856:2x 2x 2x 107
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 3x 11 = 264
Therefore, the value for common factors is 264.
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 = 82075154496192/(1x264)
LCM = 82075154496192/264
LCM = 310890736728
Thus, we can understand that the LCM of 814,789,234,638,856 is 310890736728.
