Find LCM of 792,408,209,931,838 with Prime Factorization
| 2 | 792, 408, 209, 931, 838 |
| 2 | 396, 204, 209, 931, 419 |
| 2 | 198, 102, 209, 931, 419 |
| 3 | 99, 51, 209, 931, 419 |
| 11 | 33, 17, 209, 931, 419 |
| 19 | 3, 17, 19, 931, 419 |
| 3, 17, 1, 49, 419 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 11 x 19 x 3 x 17 x 1 x 49 x 419 = 5252158296
Therefore, the lowest common multiple of 792,408,209,931,838 is 5252158296.
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.
792 x 408 x 209 x 931 x 838 = 52689652025472
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.
792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
209 : 1, 11, 19, 209
931 : 1, 7, 19, 49, 133, 931
838 : 1, 2, 419, 838
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 792,408,209,931,838, is 1.
Now, the common factors can be found like this.
792:2x 2x 2x 3x 3x 11
408:2x 2x 2x 3x 17
209:11x 19
931:7x 7x 19
838:2x 419
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 3x 11x 19 = 10032
Therefore, the value for common factors is 10032.
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 = 52689652025472/(1x10032)
LCM = 52689652025472/10032
LCM = 5252158296
Thus, we can understand that the LCM of 792,408,209,931,838 is 5252158296.
