Find LCM of 643,984,536,451,288 with Prime Factorization
| 2 | 643, 984, 536, 451, 288 |
| 2 | 643, 492, 268, 451, 144 |
| 2 | 643, 246, 134, 451, 72 |
| 3 | 643, 123, 67, 451, 36 |
| 41 | 643, 41, 67, 451, 12 |
| 643, 1, 67, 11, 12 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 41 x 643 x 1 x 67 x 11 x 12 = 5595704928
Therefore, the lowest common multiple of 643,984,536,451,288 is 5595704928.
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.
643 x 984 x 536 x 451 x 288 = 44049389193216
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.
643 : 1, 643
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
536 : 1, 2, 4, 8, 67, 134, 268, 536
451 : 1, 11, 41, 451
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,984,536,451,288, is 1.
Now, the common factors can be found like this.
643:643
984:2x 2x 2x 3x 41
536:2x 2x 2x 67
451:11x 41
288:2x 2x 2x 2x 2x 3x 3
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 3x 41 = 7872
Therefore, the value for common factors is 7872.
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 = 44049389193216/(1x7872)
LCM = 44049389193216/7872
LCM = 5595704928
Thus, we can understand that the LCM of 643,984,536,451,288 is 5595704928.
