The LCM of 391,780,832,959,899 is 4206972194880.
Find LCM of 391,780,832,959,899 with Prime Factorization
| 2 | 391, 780, 832, 959, 899 |
| 2 | 391, 390, 416, 959, 899 |
| 13 | 391, 195, 208, 959, 899 |
| 391, 15, 16, 959, 899 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 391 x 15 x 16 x 959 x 899 = 4206972194880
Therefore, the lowest common multiple of 391,780,832,959,899 is 4206972194880.
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.
391 x 780 x 832 x 959 x 899 = 218762554133760
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.
391 : 1, 17, 23, 391
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
832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832
959 : 1, 7, 137, 959
899 : 1, 29, 31, 899
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,780,832,959,899, is 1.
Now, the common factors can be found like this.
391:17x 23
780:2x 2x 3x 5x 13
832:2x 2x 2x 2x 2x 2x 13
959:7x 137
899:29x 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 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 = 218762554133760/(1x52)
LCM = 218762554133760/52
LCM = 4206972194880
Thus, we can understand that the LCM of 391,780,832,959,899 is 4206972194880.
