Given numbers are 954,780,856,845
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 954,780,856,845 is 345023640.
Find LCM of 954,780,856,845 with Prime Factorization
| 2 | 954, 780, 856, 845 |
| 2 | 477, 390, 428, 845 |
| 3 | 477, 195, 214, 845 |
| 5 | 159, 65, 214, 845 |
| 13 | 159, 13, 214, 169 |
| 159, 1, 214, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 159 x 1 x 214 x 13 = 345023640
Therefore, the lowest common multiple of 954,780,856,845 is 345023640.
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.
954 x 780 x 856 x 845 = 538236878400
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.
954 : 1, 2, 3, 6, 9, 18, 53, 106, 159, 318, 477, 954
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
856 : 1, 2, 4, 8, 107, 214, 428, 856
845 : 1, 5, 13, 65, 169, 845
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 954,780,856,845, is 1.
Now, the common factors can be found like this.
954:2x 3x 3x 53
780:2x 2x 3x 5x 13
856:2x 2x 2x 107
845:5x 13x 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 3x 5x 13 = 1560
Therefore, the value for common factors is 1560.
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 = 538236878400/(1x1560)
LCM = 538236878400/1560
LCM = 345023640
Thus, we can understand that the LCM of 954,780,856,845 is 345023640.
