Find LCM of 444,662,320,128 with Prime Factorization
| 2 | 444, 662, 320, 128 |
| 2 | 222, 331, 160, 64 |
| 2 | 111, 331, 80, 32 |
| 2 | 111, 331, 40, 16 |
| 2 | 111, 331, 20, 8 |
| 2 | 111, 331, 10, 4 |
| 111, 331, 5, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 2 x 111 x 331 x 5 x 2 = 23514240
Therefore, the lowest common multiple of 444,662,320,128 is 23514240.
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.
444 x 662 x 320 x 128 = 12039290880
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.
444 : 1, 2, 3, 4, 6, 12, 37, 74, 111, 148, 222, 444
662 : 1, 2, 331, 662
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
128 : 1, 2, 4, 8, 16, 32, 64, 128
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 444,662,320,128, is 2.
Now, the common factors can be found like this.
444:2x 2x 3x 37
662:2x 331
320:2x 2x 2x 2x 2x 2x 5
128:2x 2x 2x 2x 2x 2x 2
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 2 = 256
Therefore, the value for common factors is 256.
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 = 12039290880/(2x256)
LCM = 12039290880/512
LCM = 23514240
Thus, we can understand that the LCM of 444,662,320,128 is 23514240.
