Given numbers are 811,928,651,649,129
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 811,928,651,649,129 is 13672973477856.
Find LCM of 811,928,651,649,129 with Prime Factorization
| 3 | 811, 928, 651, 649, 129 |
| 811, 928, 217, 649, 43 |
Multiply the prime numbers at the bottom and the left side.
3 x 811 x 928 x 217 x 649 x 43 = 13672973477856
Therefore, the lowest common multiple of 811,928,651,649,129 is 13672973477856.
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 928 x 651 x 649 x 129 = 41018920433568
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
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
651 : 1, 3, 7, 21, 31, 93, 217, 651
649 : 1, 11, 59, 649
129 : 1, 3, 43, 129
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 811,928,651,649,129, is 1.
Now, the common factors can be found like this.
811:811
928:2x 2x 2x 2x 2x 29
651:3x 7x 31
649:11x 59
129:3x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 41018920433568/(1x3)
LCM = 41018920433568/3
LCM = 13672973477856
Thus, we can understand that the LCM of 811,928,651,649,129 is 13672973477856.
