Given numbers are 861,600,844,442
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 861,600,844,442 is 8029858200.
Find LCM of 861,600,844,442 with Prime Factorization
| 2 | 861, 600, 844, 442 |
| 2 | 861, 300, 422, 221 |
| 3 | 861, 150, 211, 221 |
| 287, 50, 211, 221 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 287 x 50 x 211 x 221 = 8029858200
Therefore, the lowest common multiple of 861,600,844,442 is 8029858200.
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.
861 x 600 x 844 x 442 = 192716596800
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.
861 : 1, 3, 7, 21, 41, 123, 287, 861
600 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 25, 30, 40, 50, 60, 75, 100, 120, 150, 200, 300, 600
844 : 1, 2, 4, 211, 422, 844
442 : 1, 2, 13, 17, 26, 34, 221, 442
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,600,844,442, is 1.
Now, the common factors can be found like this.
861:3x 7x 41
600:2x 2x 2x 3x 5x 5
844:2x 2x 211
442:2x 13x 17
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 2x 3 = 24
Therefore, the value for common factors is 24.
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 = 192716596800/(1x24)
LCM = 192716596800/24
LCM = 8029858200
Thus, we can understand that the LCM of 861,600,844,442 is 8029858200.
