Given numbers are 811,807,811,657
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 811,807,811,657 is 143330463.
Find LCM of 811,807,811,657 with Prime Factorization
| 3 | 811, 807, 811, 657 |
| 811 | 811, 269, 811, 219 |
| 1, 269, 1, 219 |
Multiply the prime numbers at the bottom and the left side.
3 x 811 x 1 x 269 x 1 x 219 = 143330463
Therefore, the lowest common multiple of 811,807,811,657 is 143330463.
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 807 x 811 x 657 = 348723016479
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
807 : 1, 3, 269, 807
811 : 1, 811
657 : 1, 3, 9, 73, 219, 657
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 811,807,811,657, is 1.
Now, the common factors can be found like this.
811:811
807:3x 269
811:811
657:3x 3x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 811 = 2433
Therefore, the value for common factors is 2433.
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 = 348723016479/(1x2433)
LCM = 348723016479/2433
LCM = 143330463
Thus, we can understand that the LCM of 811,807,811,657 is 143330463.
