Given numbers are 780,778,806,313
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 780,778,806,313 is 2944084260.
Find LCM of 780,778,806,313 with Prime Factorization
| 2 | 780, 778, 806, 313 |
| 13 | 390, 389, 403, 313 |
| 30, 389, 31, 313 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 30 x 389 x 31 x 313 = 2944084260
Therefore, the lowest common multiple of 780,778,806,313 is 2944084260.
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 778 x 806 x 313 = 153092381520
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
778 : 1, 2, 389, 778
806 : 1, 2, 13, 26, 31, 62, 403, 806
313 : 1, 313
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,778,806,313, is 1.
Now, the common factors can be found like this.
780:2x 2x 3x 5x 13
778:2x 389
806:2x 13x 31
313:313
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 13 = 52
Therefore, the value for common factors is 52.
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 = 153092381520/(1x52)
LCM = 153092381520/52
LCM = 2944084260
Thus, we can understand that the LCM of 780,778,806,313 is 2944084260.
