Given numbers are 396,616,786,515
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 396,616,786,515 is 374025960.
Find LCM of 396,616,786,515 with Prime Factorization
| 2 | 396, 616, 786, 515 |
| 2 | 198, 308, 393, 515 |
| 3 | 99, 154, 393, 515 |
| 11 | 33, 154, 131, 515 |
| 3, 14, 131, 515 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 3 x 14 x 131 x 515 = 374025960
Therefore, the lowest common multiple of 396,616,786,515 is 374025960.
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.
396 x 616 x 786 x 515 = 98742853440
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.
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
786 : 1, 2, 3, 6, 131, 262, 393, 786
515 : 1, 5, 103, 515
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 396,616,786,515, is 1.
Now, the common factors can be found like this.
396:2x 2x 3x 3x 11
616:2x 2x 2x 7x 11
786:2x 3x 131
515:5x 103
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 = 98742853440/(1x264)
LCM = 98742853440/264
LCM = 374025960
Thus, we can understand that the LCM of 396,616,786,515 is 374025960.
