Find LCM of 860,581,840,273,731 with Prime Factorization
| 2 | 860, 581, 840, 273, 731 |
| 2 | 430, 581, 420, 273, 731 |
| 3 | 215, 581, 210, 273, 731 |
| 5 | 215, 581, 70, 91, 731 |
| 7 | 43, 581, 14, 91, 731 |
| 43 | 43, 83, 2, 13, 731 |
| 1, 83, 2, 13, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 43 x 1 x 83 x 2 x 13 x 17 = 662549160
Therefore, the lowest common multiple of 860,581,840,273,731 is 662549160.
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.
860 x 581 x 840 x 273 x 731 = 83759464807200
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.
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
581 : 1, 7, 83, 581
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
273 : 1, 3, 7, 13, 21, 39, 91, 273
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 860,581,840,273,731, is 1.
Now, the common factors can be found like this.
860:2x 2x 5x 43
581:7x 83
840:2x 2x 2x 3x 5x 7
273:3x 7x 13
731:17x 43
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 3x 5x 7x 7x 43 = 126420
Therefore, the value for common factors is 126420.
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 = 83759464807200/(1x126420)
LCM = 83759464807200/126420
LCM = 662549160
Thus, we can understand that the LCM of 860,581,840,273,731 is 662549160.
