Given numbers are 7,780,806,536
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 7,780,806,536 is 22680840.
Find LCM of 7,780,806,536 with Prime Factorization
| 2 | 7, 780, 806, 536 |
| 2 | 7, 390, 403, 268 |
| 13 | 7, 195, 403, 134 |
| 7, 15, 31, 134 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 7 x 15 x 31 x 134 = 22680840
Therefore, the lowest common multiple of 7,780,806,536 is 22680840.
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.
7 x 780 x 806 x 536 = 2358807360
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.
7 : 1, 7
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
806 : 1, 2, 13, 26, 31, 62, 403, 806
536 : 1, 2, 4, 8, 67, 134, 268, 536
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7,780,806,536, is 1.
Now, the common factors can be found like this.
7:7
780:2x 2x 3x 5x 13
806:2x 13x 31
536:2x 2x 2x 67
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 13 = 104
Therefore, the value for common factors is 104.
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 = 2358807360/(1x104)
LCM = 2358807360/104
LCM = 22680840
Thus, we can understand that the LCM of 7,780,806,536 is 22680840.
