Find LCM of 814,631,407,804,987 with Prime Factorization
| 2 | 814, 631, 407, 804, 987 |
| 3 | 407, 631, 407, 402, 987 |
| 11 | 407, 631, 407, 134, 329 |
| 37 | 37, 631, 37, 134, 329 |
| 1, 631, 1, 134, 329 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 37 x 1 x 631 x 1 x 134 x 329 = 67932205572
Therefore, the lowest common multiple of 814,631,407,804,987 is 67932205572.
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 631 x 407 x 804 x 987 = 165890446006824
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
631 : 1, 631
407 : 1, 11, 37, 407
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
987 : 1, 3, 7, 21, 47, 141, 329, 987
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 814,631,407,804,987, is 1.
Now, the common factors can be found like this.
814:2x 11x 37
631:631
407:11x 37
804:2x 2x 3x 67
987:3x 7x 47
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 11x 37 = 2442
Therefore, the value for common factors is 2442.
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 = 165890446006824/(1x2442)
LCM = 165890446006824/2442
LCM = 67932205572
Thus, we can understand that the LCM of 814,631,407,804,987 is 67932205572.
