Given numbers are 780,949,663,754,806
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 780,949,663,754,806 is 870214020.
Find LCM of 780,949,663,754,806 with Prime Factorization
| 2 | 780, 949, 663, 754, 806 |
| 3 | 390, 949, 663, 377, 403 |
| 13 | 130, 949, 221, 377, 403 |
| 10, 73, 17, 29, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 10 x 73 x 17 x 29 x 31 = 870214020
Therefore, the lowest common multiple of 780,949,663,754,806 is 870214020.
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.
780 x 949 x 663 x 754 x 806 = 298250191502640
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.
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
949 : 1, 13, 73, 949
663 : 1, 3, 13, 17, 39, 51, 221, 663
754 : 1, 2, 13, 26, 29, 58, 377, 754
806 : 1, 2, 13, 26, 31, 62, 403, 806
13 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,949,663,754,806, is 13.
Now, the common factors can be found like this.
780:2x 2x 3x 5x 13
949:13x 73
663:3x 13x 17
754:2x 13x 29
806:2x 13x 31
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 3x 13x 13x 13 = 26364
Therefore, the value for common factors is 26364.
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 = 298250191502640/(13x26364)
LCM = 298250191502640/342732
LCM = 870214020
Thus, we can understand that the LCM of 780,949,663,754,806 is 870214020.
