Given numbers are 811,622,548,685,351
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 811,622,548,685,351 is 242571024540.
Find LCM of 811,622,548,685,351 with Prime Factorization
| 2 | 811, 622, 548, 685, 351 |
| 137 | 811, 311, 274, 685, 351 |
| 811, 311, 2, 5, 351 |
Multiply the prime numbers at the bottom and the left side.
2 x 137 x 811 x 311 x 2 x 5 x 351 = 242571024540
Therefore, the lowest common multiple of 811,622,548,685,351 is 242571024540.
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.
811 x 622 x 548 x 685 x 351 = 66464460723960
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.
811 : 1, 811
622 : 1, 2, 311, 622
548 : 1, 2, 4, 137, 274, 548
685 : 1, 5, 137, 685
351 : 1, 3, 9, 13, 27, 39, 117, 351
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 811,622,548,685,351, is 1.
Now, the common factors can be found like this.
811:811
622:2x 311
548:2x 2x 137
685:5x 137
351:3x 3x 3x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 137 = 274
Therefore, the value for common factors is 274.
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 = 66464460723960/(1x274)
LCM = 66464460723960/274
LCM = 242571024540
Thus, we can understand that the LCM of 811,622,548,685,351 is 242571024540.
