The LCM of 720,377,780,815 is 44244720.
Find LCM of 720,377,780,815 with Prime Factorization
| 2 | 720, 377, 780, 815 |
| 2 | 360, 377, 390, 815 |
| 3 | 180, 377, 195, 815 |
| 5 | 60, 377, 65, 815 |
| 13 | 12, 377, 13, 163 |
| 12, 29, 1, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 12 x 29 x 1 x 163 = 44244720
Therefore, the lowest common multiple of 720,377,780,815 is 44244720.
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.
720 x 377 x 780 x 815 = 172554408000
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.
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
377 : 1, 13, 29, 377
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
815 : 1, 5, 163, 815
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,377,780,815, is 1.
Now, the common factors can be found like this.
720:2x 2x 2x 2x 3x 3x 5
377:13x 29
780:2x 2x 3x 5x 13
815:5x 163
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 5x 5x 13 = 3900
Therefore, the value for common factors is 3900.
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 = 172554408000/(1x3900)
LCM = 172554408000/3900
LCM = 44244720
Thus, we can understand that the LCM of 720,377,780,815 is 44244720.
