Given numbers are 811,171,893,705
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 811,171,893,705 is 32590035.
Find LCM of 811,171,893,705 with Prime Factorization
| 3 | 811, 171, 893, 705 |
| 19 | 811, 57, 893, 235 |
| 47 | 811, 3, 47, 235 |
| 811, 3, 1, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 19 x 47 x 811 x 3 x 1 x 5 = 32590035
Therefore, the lowest common multiple of 811,171,893,705 is 32590035.
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 171 x 893 x 705 = 87308703765
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
171 : 1, 3, 9, 19, 57, 171
893 : 1, 19, 47, 893
705 : 1, 3, 5, 15, 47, 141, 235, 705
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 811,171,893,705, is 1.
Now, the common factors can be found like this.
811:811
171:3x 3x 19
893:19x 47
705:3x 5x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 19x 47 = 2679
Therefore, the value for common factors is 2679.
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 = 87308703765/(1x2679)
LCM = 87308703765/2679
LCM = 32590035
Thus, we can understand that the LCM of 811,171,893,705 is 32590035.
