Given numbers are 913,448,916,781,731
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 913,448,916,781,731 is 4861384808896.
Find LCM of 913,448,916,781,731 with Prime Factorization
| 2 | 913, 448, 916, 781, 731 |
| 2 | 913, 224, 458, 781, 731 |
| 11 | 913, 112, 229, 781, 731 |
| 83, 112, 229, 71, 731 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 83 x 112 x 229 x 71 x 731 = 4861384808896
Therefore, the lowest common multiple of 913,448,916,781,731 is 4861384808896.
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 448 x 916 x 781 x 731 = 213900931591424
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
448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
916 : 1, 2, 4, 229, 458, 916
781 : 1, 11, 71, 781
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 913,448,916,781,731, is 1.
Now, the common factors can be found like this.
913:11x 83
448:2x 2x 2x 2x 2x 2x 7
916:2x 2x 229
781:11x 71
731:17x 43
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 11 = 44
Therefore, the value for common factors is 44.
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 = 213900931591424/(1x44)
LCM = 213900931591424/44
LCM = 4861384808896
Thus, we can understand that the LCM of 913,448,916,781,731 is 4861384808896.
