Find LCM of 910,872,489,728 with Prime Factorization
| 2 | 910, 872, 489, 728 |
| 2 | 455, 436, 489, 364 |
| 2 | 455, 218, 489, 182 |
| 7 | 455, 109, 489, 91 |
| 13 | 65, 109, 489, 13 |
| 5, 109, 489, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 13 x 5 x 109 x 489 x 1 = 194015640
Therefore, the lowest common multiple of 910,872,489,728 is 194015640.
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.
910 x 872 x 489 x 728 = 282486771840
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.
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
872 : 1, 2, 4, 8, 109, 218, 436, 872
489 : 1, 3, 163, 489
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 910,872,489,728, is 1.
Now, the common factors can be found like this.
910:2x 5x 7x 13
872:2x 2x 2x 109
489:3x 163
728:2x 2x 2x 7x 13
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 7x 13 = 1456
Therefore, the value for common factors is 1456.
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 = 282486771840/(1x1456)
LCM = 282486771840/1456
LCM = 194015640
Thus, we can understand that the LCM of 910,872,489,728 is 194015640.
