Given numbers are 811,217,511,571,685
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 811,217,511,571,685 is 5024931292885.
Find LCM of 811,217,511,571,685 with Prime Factorization
| 7 | 811, 217, 511, 571, 685 |
| 811, 31, 73, 571, 685 |
Multiply the prime numbers at the bottom and the left side.
7 x 811 x 31 x 73 x 571 x 685 = 5024931292885
Therefore, the lowest common multiple of 811,217,511,571,685 is 5024931292885.
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 217 x 511 x 571 x 685 = 35174519050195
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
217 : 1, 7, 31, 217
511 : 1, 7, 73, 511
571 : 1, 571
685 : 1, 5, 137, 685
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 811,217,511,571,685, is 1.
Now, the common factors can be found like this.
811:811
217:7x 31
511:7x 73
571:571
685:5x 137
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7 = 7
Therefore, the value for common factors is 7.
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 = 35174519050195/(1x7)
LCM = 35174519050195/7
LCM = 5024931292885
Thus, we can understand that the LCM of 811,217,511,571,685 is 5024931292885.
