Given numbers are 814,688,848,320
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 814,688,848,320 is 296816960.
Find LCM of 814,688,848,320 with Prime Factorization
| 2 | 814, 688, 848, 320 |
| 2 | 407, 344, 424, 160 |
| 2 | 407, 172, 212, 80 |
| 2 | 407, 86, 106, 40 |
| 407, 43, 53, 20 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 407 x 43 x 53 x 20 = 296816960
Therefore, the lowest common multiple of 814,688,848,320 is 296816960.
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 688 x 848 x 320 = 151970283520
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
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
848 : 1, 2, 4, 8, 16, 53, 106, 212, 424, 848
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 814,688,848,320, is 2.
Now, the common factors can be found like this.
814:2x 11x 37
688:2x 2x 2x 2x 43
848:2x 2x 2x 2x 53
320:2x 2x 2x 2x 2x 2x 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 2x 2x 2x 2 = 256
Therefore, the value for common factors is 256.
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 = 151970283520/(2x256)
LCM = 151970283520/512
LCM = 296816960
Thus, we can understand that the LCM of 814,688,848,320 is 296816960.
