Given numbers are 584,821,388,870
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 584,821,388,870 is 20230983480.
Find LCM of 584,821,388,870 with Prime Factorization
| 2 | 584, 821, 388, 870 |
| 2 | 292, 821, 194, 435 |
| 146, 821, 97, 435 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 146 x 821 x 97 x 435 = 20230983480
Therefore, the lowest common multiple of 584,821,388,870 is 20230983480.
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.
584 x 821 x 388 x 870 = 161847867840
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.
584 : 1, 2, 4, 8, 73, 146, 292, 584
821 : 1, 821
388 : 1, 2, 4, 97, 194, 388
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 584,821,388,870, is 1.
Now, the common factors can be found like this.
584:2x 2x 2x 73
821:821
388:2x 2x 97
870:2x 3x 5x 29
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 2 = 8
Therefore, the value for common factors is 8.
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 = 161847867840/(1x8)
LCM = 161847867840/8
LCM = 20230983480
Thus, we can understand that the LCM of 584,821,388,870 is 20230983480.
