Given numbers are 517,818,921,441,218
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 517,818,921,441,218 is 6240901233798.
Find LCM of 517,818,921,441,218 with Prime Factorization
| 2 | 517, 818, 921, 441, 218 |
| 3 | 517, 409, 921, 441, 109 |
| 517, 409, 307, 147, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 517 x 409 x 307 x 147 x 109 = 6240901233798
Therefore, the lowest common multiple of 517,818,921,441,218 is 6240901233798.
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 818 x 921 x 441 x 218 = 37445407402788
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
818 : 1, 2, 409, 818
921 : 1, 3, 307, 921
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
218 : 1, 2, 109, 218
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 517,818,921,441,218, is 1.
Now, the common factors can be found like this.
517:11x 47
818:2x 409
921:3x 307
441:3x 3x 7x 7
218:2x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 37445407402788/(1x6)
LCM = 37445407402788/6
LCM = 6240901233798
Thus, we can understand that the LCM of 517,818,921,441,218 is 6240901233798.
