Given numbers are 813,989,529,842
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 813,989,529,842 is 15571367862.
Find LCM of 813,989,529,842 with Prime Factorization
| 23 | 813, 989, 529, 842 |
| 813, 43, 23, 842 |
Multiply the prime numbers at the bottom and the left side.
23 x 813 x 43 x 23 x 842 = 15571367862
Therefore, the lowest common multiple of 813,989,529,842 is 15571367862.
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.
813 x 989 x 529 x 842 = 358141460826
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.
813 : 1, 3, 271, 813
989 : 1, 23, 43, 989
529 : 1, 23, 529
842 : 1, 2, 421, 842
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,989,529,842, is 1.
Now, the common factors can be found like this.
813:3x 271
989:23x 43
529:23x 23
842:2x 421
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23 = 23
Therefore, the value for common factors is 23.
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 = 358141460826/(1x23)
LCM = 358141460826/23
LCM = 15571367862
Thus, we can understand that the LCM of 813,989,529,842 is 15571367862.
