Given numbers are 814,312,960,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 814,312,960,781 is 360634560.
Find LCM of 814,312,960,781 with Prime Factorization
| 2 | 814, 312, 960, 781 |
| 2 | 407, 156, 480, 781 |
| 2 | 407, 78, 240, 781 |
| 3 | 407, 39, 120, 781 |
| 11 | 407, 13, 40, 781 |
| 37, 13, 40, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 11 x 37 x 13 x 40 x 71 = 360634560
Therefore, the lowest common multiple of 814,312,960,781 is 360634560.
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.
814 x 312 x 960 x 781 = 190415047680
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.
814 : 1, 2, 11, 22, 37, 74, 407, 814
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 814,312,960,781, is 1.
Now, the common factors can be found like this.
814:2x 11x 37
312:2x 2x 2x 3x 13
960:2x 2x 2x 2x 2x 2x 3x 5
781:11x 71
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 2x 2x 3x 11 = 528
Therefore, the value for common factors is 528.
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 = 190415047680/(1x528)
LCM = 190415047680/528
LCM = 360634560
Thus, we can understand that the LCM of 814,312,960,781 is 360634560.
