Given numbers are 581,417,913,814
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 581,417,913,814 is 197213478.
Find LCM of 581,417,913,814 with Prime Factorization
| 11 | 581, 417, 913, 814 |
| 83 | 581, 417, 83, 74 |
| 7, 417, 1, 74 |
Multiply the prime numbers at the bottom and the left side.
11 x 83 x 7 x 417 x 1 x 74 = 197213478
Therefore, the lowest common multiple of 581,417,913,814 is 197213478.
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.
581 x 417 x 913 x 814 = 180055905414
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.
581 : 1, 7, 83, 581
417 : 1, 3, 139, 417
913 : 1, 11, 83, 913
814 : 1, 2, 11, 22, 37, 74, 407, 814
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 581,417,913,814, is 1.
Now, the common factors can be found like this.
581:7x 83
417:3x 139
913:11x 83
814:2x 11x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 83 = 913
Therefore, the value for common factors is 913.
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 = 180055905414/(1x913)
LCM = 180055905414/913
LCM = 197213478
Thus, we can understand that the LCM of 581,417,913,814 is 197213478.
