The LCM of 478,871,979,780,239 is 12227847060.
Find LCM of 478,871,979,780,239 with Prime Factorization
| 2 | 478, 871, 979, 780, 239 |
| 13 | 239, 871, 979, 390, 239 |
| 239 | 239, 67, 979, 30, 239 |
| 1, 67, 979, 30, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 239 x 1 x 67 x 979 x 30 x 1 = 12227847060
Therefore, the lowest common multiple of 478,871,979,780,239 is 12227847060.
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.
478 x 871 x 979 x 780 x 239 = 75983841630840
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.
478 : 1, 2, 239, 478
871 : 1, 13, 67, 871
979 : 1, 11, 89, 979
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
239 : 1, 239
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,871,979,780,239, is 1.
Now, the common factors can be found like this.
478:2x 239
871:13x 67
979:11x 89
780:2x 2x 3x 5x 13
239:239
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 239 = 6214
Therefore, the value for common factors is 6214.
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 = 75983841630840/(1x6214)
LCM = 75983841630840/6214
LCM = 12227847060
Thus, we can understand that the LCM of 478,871,979,780,239 is 12227847060.
