Given numbers are 811,688,913,915,804
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 811,688,913,915,804 is 31230286383120.
Find LCM of 811,688,913,915,804 with Prime Factorization
| 2 | 811, 688, 913, 915, 804 |
| 2 | 811, 344, 913, 915, 402 |
| 3 | 811, 172, 913, 915, 201 |
| 811, 172, 913, 305, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 811 x 172 x 913 x 305 x 67 = 31230286383120
Therefore, the lowest common multiple of 811,688,913,915,804 is 31230286383120.
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 688 x 913 x 915 x 804 = 374763436597440
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
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
913 : 1, 11, 83, 913
915 : 1, 3, 5, 15, 61, 183, 305, 915
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 811,688,913,915,804, is 1.
Now, the common factors can be found like this.
811:811
688:2x 2x 2x 2x 43
913:11x 83
915:3x 5x 61
804:2x 2x 3x 67
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 3 = 12
Therefore, the value for common factors is 12.
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 = 374763436597440/(1x12)
LCM = 374763436597440/12
LCM = 31230286383120
Thus, we can understand that the LCM of 811,688,913,915,804 is 31230286383120.
