Given numbers are 827,643,642,813
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 827,643,642,813 is 92516842302.
Find LCM of 827,643,642,813 with Prime Factorization
| 3 | 827, 643, 642, 813 |
| 827, 643, 214, 271 |
Multiply the prime numbers at the bottom and the left side.
3 x 827 x 643 x 214 x 271 = 92516842302
Therefore, the lowest common multiple of 827,643,642,813 is 92516842302.
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.
827 x 643 x 642 x 813 = 277550526906
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.
827 : 1, 827
643 : 1, 643
642 : 1, 2, 3, 6, 107, 214, 321, 642
813 : 1, 3, 271, 813
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 827,643,642,813, is 1.
Now, the common factors can be found like this.
827:827
643:643
642:2x 3x 107
813:3x 271
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 = 277550526906/(1x3)
LCM = 277550526906/3
LCM = 92516842302
Thus, we can understand that the LCM of 827,643,642,813 is 92516842302.
