Find LCM of 728,837,362,522,638 with Prime Factorization
| 2 | 728, 837, 362, 522, 638 |
| 3 | 364, 837, 181, 261, 319 |
| 3 | 364, 279, 181, 87, 319 |
| 29 | 364, 93, 181, 29, 319 |
| 364, 93, 181, 1, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 29 x 364 x 93 x 181 x 1 x 11 = 35182451304
Therefore, the lowest common multiple of 728,837,362,522,638 is 35182451304.
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.
728 x 837 x 362 x 522 x 638 = 73460958322752
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.
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
837 : 1, 3, 9, 27, 31, 93, 279, 837
362 : 1, 2, 181, 362
522 : 1, 2, 3, 6, 9, 18, 29, 58, 87, 174, 261, 522
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,837,362,522,638, is 1.
Now, the common factors can be found like this.
728:2x 2x 2x 7x 13
837:3x 3x 3x 31
362:2x 181
522:2x 3x 3x 29
638:2x 11x 29
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 3x 3x 29 = 2088
Therefore, the value for common factors is 2088.
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 = 73460958322752/(1x2088)
LCM = 73460958322752/2088
LCM = 35182451304
Thus, we can understand that the LCM of 728,837,362,522,638 is 35182451304.
