Given numbers are 581,249,836,855
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 581,249,836,855 is 21857220.
Find LCM of 581,249,836,855 with Prime Factorization
| 3 | 581, 249, 836, 855 |
| 19 | 581, 83, 836, 285 |
| 83 | 581, 83, 44, 15 |
| 7, 1, 44, 15 |
Multiply the prime numbers at the bottom and the left side.
3 x 19 x 83 x 7 x 1 x 44 x 15 = 21857220
Therefore, the lowest common multiple of 581,249,836,855 is 21857220.
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 249 x 836 x 855 = 103406507820
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
249 : 1, 3, 83, 249
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 581,249,836,855, is 1.
Now, the common factors can be found like this.
581:7x 83
249:3x 83
836:2x 2x 11x 19
855:3x 3x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 19x 83 = 4731
Therefore, the value for common factors is 4731.
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 = 103406507820/(1x4731)
LCM = 103406507820/4731
LCM = 21857220
Thus, we can understand that the LCM of 581,249,836,855 is 21857220.
