Find LCM of 731,814,638,561,881 with Prime Factorization
| 2 | 731, 814, 638, 561, 881 |
| 11 | 731, 407, 319, 561, 881 |
| 17 | 731, 37, 29, 51, 881 |
| 43, 37, 29, 3, 881 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 17 x 43 x 37 x 29 x 3 x 881 = 45607570998
Therefore, the lowest common multiple of 731,814,638,561,881 is 45607570998.
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.
731 x 814 x 638 x 561 x 881 = 187629547085772
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.
731 : 1, 17, 43, 731
814 : 1, 2, 11, 22, 37, 74, 407, 814
638 : 1, 2, 11, 22, 29, 58, 319, 638
561 : 1, 3, 11, 17, 33, 51, 187, 561
881 : 1, 881
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,814,638,561,881, is 1.
Now, the common factors can be found like this.
731:17x 43
814:2x 11x 37
638:2x 11x 29
561:3x 11x 17
881:881
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 11x 17 = 4114
Therefore, the value for common factors is 4114.
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 = 187629547085772/(1x4114)
LCM = 187629547085772/4114
LCM = 45607570998
Thus, we can understand that the LCM of 731,814,638,561,881 is 45607570998.
