Given numbers are 580,696,401,812,643
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 580,696,401,812,643 is 6281055480.
Find LCM of 580,696,401,812,643 with Prime Factorization
| 2 | 580, 696, 401, 812, 643 |
| 2 | 290, 348, 401, 406, 643 |
| 29 | 145, 174, 401, 203, 643 |
| 5, 6, 401, 7, 643 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 29 x 5 x 6 x 401 x 7 x 643 = 6281055480
Therefore, the lowest common multiple of 580,696,401,812,643 is 6281055480.
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.
580 x 696 x 401 x 812 x 643 = 84517882538880
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.
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
696 : 1, 2, 3, 4, 6, 8, 12, 24, 29, 58, 87, 116, 174, 232, 348, 696
401 : 1, 401
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
643 : 1, 643
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 580,696,401,812,643, is 1.
Now, the common factors can be found like this.
580:2x 2x 5x 29
696:2x 2x 2x 3x 29
401:401
812:2x 2x 7x 29
643:643
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 29x 29 = 13456
Therefore, the value for common factors is 13456.
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 = 84517882538880/(1x13456)
LCM = 84517882538880/13456
LCM = 6281055480
Thus, we can understand that the LCM of 580,696,401,812,643 is 6281055480.
