Find LCM of 819,878,455,516,425 with Prime Factorization
| 2 | 819, 878, 455, 516, 425 |
| 3 | 819, 439, 455, 258, 425 |
| 5 | 273, 439, 455, 86, 425 |
| 7 | 273, 439, 91, 86, 85 |
| 13 | 39, 439, 13, 86, 85 |
| 3, 439, 1, 86, 85 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 13 x 3 x 439 x 1 x 86 x 85 = 26282447100
Therefore, the lowest common multiple of 819,878,455,516,425 is 26282447100.
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.
819 x 878 x 455 x 516 x 425 = 71751080583000
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.
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
878 : 1, 2, 439, 878
455 : 1, 5, 7, 13, 35, 65, 91, 455
516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516
425 : 1, 5, 17, 25, 85, 425
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 819,878,455,516,425, is 1.
Now, the common factors can be found like this.
819:3x 3x 7x 13
878:2x 439
455:5x 7x 13
516:2x 2x 3x 43
425:5x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 7x 13 = 2730
Therefore, the value for common factors is 2730.
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 = 71751080583000/(1x2730)
LCM = 71751080583000/2730
LCM = 26282447100
Thus, we can understand that the LCM of 819,878,455,516,425 is 26282447100.
