Given numbers are 616,418,780,834
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 616,418,780,834 is 317236920.
Find LCM of 616,418,780,834 with Prime Factorization
| 2 | 616, 418, 780, 834 |
| 2 | 308, 209, 390, 417 |
| 3 | 154, 209, 195, 417 |
| 11 | 154, 209, 65, 139 |
| 14, 19, 65, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 14 x 19 x 65 x 139 = 317236920
Therefore, the lowest common multiple of 616,418,780,834 is 317236920.
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 418 x 780 x 834 = 167501093760
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
418 : 1, 2, 11, 19, 22, 38, 209, 418
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
834 : 1, 2, 3, 6, 139, 278, 417, 834
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 616,418,780,834, is 2.
Now, the common factors can be found like this.
616:2x 2x 2x 7x 11
418:2x 11x 19
780:2x 2x 3x 5x 13
834:2x 3x 139
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 = 167501093760/(2x264)
LCM = 167501093760/528
LCM = 317236920
Thus, we can understand that the LCM of 616,418,780,834 is 317236920.
