Given numbers are 517,458,817,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 517,458,817,989 is 4449445726.
Find LCM of 517,458,817,989 with Prime Factorization
| 43 | 517, 458, 817, 989 |
| 517, 458, 19, 23 |
Multiply the prime numbers at the bottom and the left side.
43 x 517 x 458 x 19 x 23 = 4449445726
Therefore, the lowest common multiple of 517,458,817,989 is 4449445726.
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.
517 x 458 x 817 x 989 = 191326166218
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.
517 : 1, 11, 47, 517
458 : 1, 2, 229, 458
817 : 1, 19, 43, 817
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 517,458,817,989, is 1.
Now, the common factors can be found like this.
517:11x 47
458:2x 229
817:19x 43
989:23x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
43 = 43
Therefore, the value for common factors is 43.
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 = 191326166218/(1x43)
LCM = 191326166218/43
LCM = 4449445726
Thus, we can understand that the LCM of 517,458,817,989 is 4449445726.
