Given numbers are 844,856,617,899,780
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 844,856,617,899,780 is 19536001821960.
Find LCM of 844,856,617,899,780 with Prime Factorization
| 2 | 844, 856, 617, 899, 780 |
| 2 | 422, 428, 617, 899, 390 |
| 211, 214, 617, 899, 195 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 211 x 214 x 617 x 899 x 195 = 19536001821960
Therefore, the lowest common multiple of 844,856,617,899,780 is 19536001821960.
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.
844 x 856 x 617 x 899 x 780 = 312576029151360
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.
844 : 1, 2, 4, 211, 422, 844
856 : 1, 2, 4, 8, 107, 214, 428, 856
617 : 1, 617
899 : 1, 29, 31, 899
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 844,856,617,899,780, is 1.
Now, the common factors can be found like this.
844:2x 2x 211
856:2x 2x 2x 107
617:617
899:29x 31
780:2x 2x 3x 5x 13
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 2 = 16
Therefore, the value for common factors is 16.
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 = 312576029151360/(1x16)
LCM = 312576029151360/16
LCM = 19536001821960
Thus, we can understand that the LCM of 844,856,617,899,780 is 19536001821960.
