Given numbers are 717,781,517,436,831
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 717,781,517,436,831 is 3178588485468.
Find LCM of 717,781,517,436,831 with Prime Factorization
| 3 | 717, 781, 517, 436, 831 |
| 11 | 239, 781, 517, 436, 277 |
| 239, 71, 47, 436, 277 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 239 x 71 x 47 x 436 x 277 = 3178588485468
Therefore, the lowest common multiple of 717,781,517,436,831 is 3178588485468.
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.
717 x 781 x 517 x 436 x 831 = 104893420020444
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.
717 : 1, 3, 239, 717
781 : 1, 11, 71, 781
517 : 1, 11, 47, 517
436 : 1, 2, 4, 109, 218, 436
831 : 1, 3, 277, 831
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 717,781,517,436,831, is 1.
Now, the common factors can be found like this.
717:3x 239
781:11x 71
517:11x 47
436:2x 2x 109
831:3x 277
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11 = 33
Therefore, the value for common factors is 33.
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 = 104893420020444/(1x33)
LCM = 104893420020444/33
LCM = 3178588485468
Thus, we can understand that the LCM of 717,781,517,436,831 is 3178588485468.
