Given numbers are 539,838,484,781,990
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 539,838,484,781,990 is 31748727780.
Find LCM of 539,838,484,781,990 with Prime Factorization
| 2 | 539, 838, 484, 781, 990 |
| 11 | 539, 419, 242, 781, 495 |
| 49, 419, 22, 71, 45 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 49 x 419 x 22 x 71 x 45 = 31748727780
Therefore, the lowest common multiple of 539,838,484,781,990 is 31748727780.
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.
539 x 838 x 484 x 781 x 990 = 169030226700720
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.
539 : 1, 7, 11, 49, 77, 539
838 : 1, 2, 419, 838
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
781 : 1, 11, 71, 781
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 539,838,484,781,990, is 1.
Now, the common factors can be found like this.
539:7x 7x 11
838:2x 419
484:2x 2x 11x 11
781:11x 71
990:2x 3x 3x 5x 11
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 11x 11x 11 = 5324
Therefore, the value for common factors is 5324.
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 = 169030226700720/(1x5324)
LCM = 169030226700720/5324
LCM = 31748727780
Thus, we can understand that the LCM of 539,838,484,781,990 is 31748727780.
