The LCM of 408,547,848,720 is 354849840.
Find LCM of 408,547,848,720 with Prime Factorization
| 2 | 408, 547, 848, 720 |
| 2 | 204, 547, 424, 360 |
| 2 | 102, 547, 212, 180 |
| 2 | 51, 547, 106, 90 |
| 3 | 51, 547, 53, 45 |
| 17, 547, 53, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 17 x 547 x 53 x 15 = 354849840
Therefore, the lowest common multiple of 408,547,848,720 is 354849840.
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.
408 x 547 x 848 x 720 = 136262338560
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.
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
547 : 1, 547
848 : 1, 2, 4, 8, 16, 53, 106, 212, 424, 848
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 408,547,848,720, is 1.
Now, the common factors can be found like this.
408:2x 2x 2x 3x 17
547:547
848:2x 2x 2x 2x 53
720:2x 2x 2x 2x 3x 3x 5
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 2x 3 = 384
Therefore, the value for common factors is 384.
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 = 136262338560/(1x384)
LCM = 136262338560/384
LCM = 354849840
Thus, we can understand that the LCM of 408,547,848,720 is 354849840.
