The LCM of 128,408,245,528 is 17592960.
Find LCM of 128,408,245,528 with Prime Factorization
| 2 | 128, 408, 245, 528 |
| 2 | 64, 204, 245, 264 |
| 2 | 32, 102, 245, 132 |
| 2 | 16, 51, 245, 66 |
| 3 | 8, 51, 245, 33 |
| 8, 17, 245, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 8 x 17 x 245 x 11 = 17592960
Therefore, the lowest common multiple of 128,408,245,528 is 17592960.
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 408 x 245 x 528 = 6755696640
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
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
245 : 1, 5, 7, 35, 49, 245
528 : 1, 2, 3, 4, 6, 8, 11, 12, 16, 22, 24, 33, 44, 48, 66, 88, 132, 176, 264, 528
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,408,245,528, is 1.
Now, the common factors can be found like this.
128:2x 2x 2x 2x 2x 2x 2
408:2x 2x 2x 3x 17
245:5x 7x 7
528:2x 2x 2x 2x 3x 11
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 = 6755696640/(1x384)
LCM = 6755696640/384
LCM = 17592960
Thus, we can understand that the LCM of 128,408,245,528 is 17592960.
