Find LCM of 267,204,395,643,440 with Prime Factorization
| 2 | 267, 204, 395, 643, 440 |
| 2 | 267, 102, 395, 643, 220 |
| 3 | 267, 51, 395, 643, 110 |
| 5 | 89, 17, 395, 643, 110 |
| 89, 17, 79, 643, 22 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 89 x 17 x 79 x 643 x 22 = 101449736520
Therefore, the lowest common multiple of 267,204,395,643,440 is 101449736520.
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.
267 x 204 x 395 x 643 x 440 = 6086984191200
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.
267 : 1, 3, 89, 267
204 : 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204
395 : 1, 5, 79, 395
643 : 1, 643
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 267,204,395,643,440, is 1.
Now, the common factors can be found like this.
267:3x 89
204:2x 2x 3x 17
395:5x 79
643:643
440:2x 2x 2x 5x 11
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 3x 5 = 60
Therefore, the value for common factors is 60.
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 = 6086984191200/(1x60)
LCM = 6086984191200/60
LCM = 101449736520
Thus, we can understand that the LCM of 267,204,395,643,440 is 101449736520.
