Find LCM of 518,168,808,731,281 with Prime Factorization
| 2 | 518, 168, 808, 731, 281 |
| 2 | 259, 84, 404, 731, 281 |
| 2 | 259, 42, 202, 731, 281 |
| 7 | 259, 21, 101, 731, 281 |
| 37, 3, 101, 731, 281 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 37 x 3 x 101 x 731 x 281 = 128960312376
Therefore, the lowest common multiple of 518,168,808,731,281 is 128960312376.
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.
518 x 168 x 808 x 731 x 281 = 14443554986112
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.
518 : 1, 2, 7, 14, 37, 74, 259, 518
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
808 : 1, 2, 4, 8, 101, 202, 404, 808
731 : 1, 17, 43, 731
281 : 1, 281
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 518,168,808,731,281, is 1.
Now, the common factors can be found like this.
518:2x 7x 37
168:2x 2x 2x 3x 7
808:2x 2x 2x 101
731:17x 43
281:281
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 2x 7 = 112
Therefore, the value for common factors is 112.
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 = 14443554986112/(1x112)
LCM = 14443554986112/112
LCM = 128960312376
Thus, we can understand that the LCM of 518,168,808,731,281 is 128960312376.
