The LCM of 920,781,814,480 is 319022880.
Find LCM of 920,781,814,480 with Prime Factorization
| 2 | 920, 781, 814, 480 |
| 2 | 460, 781, 407, 240 |
| 2 | 230, 781, 407, 120 |
| 5 | 115, 781, 407, 60 |
| 11 | 23, 781, 407, 12 |
| 23, 71, 37, 12 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 11 x 23 x 71 x 37 x 12 = 319022880
Therefore, the lowest common multiple of 920,781,814,480 is 319022880.
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.
920 x 781 x 814 x 480 = 280740134400
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.
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
781 : 1, 11, 71, 781
814 : 1, 2, 11, 22, 37, 74, 407, 814
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,781,814,480, is 1.
Now, the common factors can be found like this.
920:2x 2x 2x 5x 23
781:11x 71
814:2x 11x 37
480:2x 2x 2x 2x 2x 3x 5
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 5x 11 = 880
Therefore, the value for common factors is 880.
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 = 280740134400/(1x880)
LCM = 280740134400/880
LCM = 319022880
Thus, we can understand that the LCM of 920,781,814,480 is 319022880.
