Given numbers are 543,693,915,826,816
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 543,693,915,826,816 is 613949379120.
Find LCM of 543,693,915,826,816 with Prime Factorization
| 2 | 543, 693, 915, 826, 816 |
| 3 | 543, 693, 915, 413, 408 |
| 7 | 181, 231, 305, 413, 136 |
| 181, 33, 305, 59, 136 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 181 x 33 x 305 x 59 x 136 = 613949379120
Therefore, the lowest common multiple of 543,693,915,826,816 is 613949379120.
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.
543 x 693 x 915 x 826 x 816 = 232072865307360
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.
543 : 1, 3, 181, 543
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
915 : 1, 3, 5, 15, 61, 183, 305, 915
826 : 1, 2, 7, 14, 59, 118, 413, 826
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 543,693,915,826,816, is 1.
Now, the common factors can be found like this.
543:3x 181
693:3x 3x 7x 11
915:3x 5x 61
826:2x 7x 59
816:2x 2x 2x 2x 3x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 7 = 378
Therefore, the value for common factors is 378.
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 = 232072865307360/(1x378)
LCM = 232072865307360/378
LCM = 613949379120
Thus, we can understand that the LCM of 543,693,915,826,816 is 613949379120.
