Given numbers are 517,818,198,688,121
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 517,818,198,688,121 is 14402486736.
Find LCM of 517,818,198,688,121 with Prime Factorization
| 2 | 517, 818, 198, 688, 121 |
| 11 | 517, 409, 99, 344, 121 |
| 47, 409, 9, 344, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 47 x 409 x 9 x 344 x 11 = 14402486736
Therefore, the lowest common multiple of 517,818,198,688,121 is 14402486736.
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 198 x 688 x 121 = 6970803580224
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
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
121 : 1, 11, 121
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 517,818,198,688,121, is 1.
Now, the common factors can be found like this.
517:11x 47
818:2x 409
198:2x 3x 3x 11
688:2x 2x 2x 2x 43
121:11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 11x 11 = 484
Therefore, the value for common factors is 484.
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 = 6970803580224/(1x484)
LCM = 6970803580224/484
LCM = 14402486736
Thus, we can understand that the LCM of 517,818,198,688,121 is 14402486736.
