Find LCM of 315,539,498,121,891 with Prime Factorization
| 3 | 315, 539, 498, 121, 891 |
| 3 | 105, 539, 166, 121, 297 |
| 7 | 35, 539, 166, 121, 99 |
| 11 | 5, 77, 166, 121, 99 |
| 5, 7, 166, 11, 9 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 11 x 5 x 7 x 166 x 11 x 9 = 398606670
Therefore, the lowest common multiple of 315,539,498,121,891 is 398606670.
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.
315 x 539 x 498 x 121 x 891 = 9115735936230
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.
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
539 : 1, 7, 11, 49, 77, 539
498 : 1, 2, 3, 6, 83, 166, 249, 498
121 : 1, 11, 121
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 315,539,498,121,891, is 1.
Now, the common factors can be found like this.
315:3x 3x 5x 7
539:7x 7x 11
498:2x 3x 83
121:11x 11
891:3x 3x 3x 3x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 7x 11x 11 = 22869
Therefore, the value for common factors is 22869.
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 = 9115735936230/(1x22869)
LCM = 9115735936230/22869
LCM = 398606670
Thus, we can understand that the LCM of 315,539,498,121,891 is 398606670.
