Given numbers are 913,103,891,462
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 913,103,891,462 is 106640226.
Find LCM of 913,103,891,462 with Prime Factorization
| 3 | 913, 103, 891, 462 |
| 11 | 913, 103, 297, 154 |
| 83, 103, 27, 14 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 83 x 103 x 27 x 14 = 106640226
Therefore, the lowest common multiple of 913,103,891,462 is 106640226.
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.
913 x 103 x 891 x 462 = 38710402038
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.
913 : 1, 11, 83, 913
103 : 1, 103
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 913,103,891,462, is 1.
Now, the common factors can be found like this.
913:11x 83
103:103
891:3x 3x 3x 3x 11
462:2x 3x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 11 = 363
Therefore, the value for common factors is 363.
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 = 38710402038/(1x363)
LCM = 38710402038/363
LCM = 106640226
Thus, we can understand that the LCM of 913,103,891,462 is 106640226.
