The LCM of 128,726,624,441 is 88792704.
Find LCM of 128,726,624,441 with Prime Factorization
| 2 | 128, 726, 624, 441 |
| 2 | 64, 363, 312, 441 |
| 2 | 32, 363, 156, 441 |
| 2 | 16, 363, 78, 441 |
| 3 | 8, 363, 39, 441 |
| 8, 121, 13, 147 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 8 x 121 x 13 x 147 = 88792704
Therefore, the lowest common multiple of 128,726,624,441 is 88792704.
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.
128 x 726 x 624 x 441 = 25572298752
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.
128 : 1, 2, 4, 8, 16, 32, 64, 128
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,726,624,441, is 1.
Now, the common factors can be found like this.
128:2x 2x 2x 2x 2x 2x 2
726:2x 3x 11x 11
624:2x 2x 2x 2x 3x 13
441:3x 3x 7x 7
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 3x 3 = 288
Therefore, the value for common factors is 288.
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 = 25572298752/(1x288)
LCM = 25572298752/288
LCM = 88792704
Thus, we can understand that the LCM of 128,726,624,441 is 88792704.
