Find LCM of 643,600,538,872,804 with Prime Factorization
| 2 | 643, 600, 538, 872, 804 |
| 2 | 643, 300, 269, 436, 402 |
| 2 | 643, 150, 269, 218, 201 |
| 3 | 643, 75, 269, 109, 201 |
| 643, 25, 269, 109, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 643 x 25 x 269 x 109 x 67 = 757906800600
Therefore, the lowest common multiple of 643,600,538,872,804 is 757906800600.
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 600 x 538 x 872 x 804 = 145518105715200
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
600 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 25, 30, 40, 50, 60, 75, 100, 120, 150, 200, 300, 600
538 : 1, 2, 269, 538
872 : 1, 2, 4, 8, 109, 218, 436, 872
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,600,538,872,804, is 1.
Now, the common factors can be found like this.
643:643
600:2x 2x 2x 3x 5x 5
538:2x 269
872:2x 2x 2x 109
804:2x 2x 3x 67
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 3 = 192
Therefore, the value for common factors is 192.
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 = 145518105715200/(1x192)
LCM = 145518105715200/192
LCM = 757906800600
Thus, we can understand that the LCM of 643,600,538,872,804 is 757906800600.
