The LCM of 426,206,781,523,861 is 72447448458.
Find LCM of 426,206,781,523,861 with Prime Factorization
| 2 | 426, 206, 781, 523, 861 |
| 3 | 213, 103, 781, 523, 861 |
| 71 | 71, 103, 781, 523, 287 |
| 1, 103, 11, 523, 287 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 71 x 1 x 103 x 11 x 523 x 287 = 72447448458
Therefore, the lowest common multiple of 426,206,781,523,861 is 72447448458.
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.
426 x 206 x 781 x 523 x 861 = 30862613043108
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.
426 : 1, 2, 3, 6, 71, 142, 213, 426
206 : 1, 2, 103, 206
781 : 1, 11, 71, 781
523 : 1, 523
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 426,206,781,523,861, is 1.
Now, the common factors can be found like this.
426:2x 3x 71
206:2x 103
781:11x 71
523:523
861:3x 7x 41
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 71 = 426
Therefore, the value for common factors is 426.
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 = 30862613043108/(1x426)
LCM = 30862613043108/426
LCM = 72447448458
Thus, we can understand that the LCM of 426,206,781,523,861 is 72447448458.
