Given numbers are 816,657,382,802
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 816,657,382,802 is 13687118064.
Find LCM of 816,657,382,802 with Prime Factorization
| 2 | 816, 657, 382, 802 |
| 3 | 408, 657, 191, 401 |
| 136, 219, 191, 401 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 136 x 219 x 191 x 401 = 13687118064
Therefore, the lowest common multiple of 816,657,382,802 is 13687118064.
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.
816 x 657 x 382 x 802 = 164245416768
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.
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
657 : 1, 3, 9, 73, 219, 657
382 : 1, 2, 191, 382
802 : 1, 2, 401, 802
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,657,382,802, is 1.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
657:3x 3x 73
382:2x 191
802:2x 401
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 3 = 12
Therefore, the value for common factors is 12.
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 = 164245416768/(1x12)
LCM = 164245416768/12
LCM = 13687118064
Thus, we can understand that the LCM of 816,657,382,802 is 13687118064.
