Find LCM of 985,928,288,571 with Prime Factorization
| 2 | 985, 928, 288, 571 |
| 2 | 985, 464, 144, 571 |
| 2 | 985, 232, 72, 571 |
| 2 | 985, 116, 36, 571 |
| 2 | 985, 58, 18, 571 |
| 985, 29, 9, 571 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 985 x 29 x 9 x 571 = 4697457120
Therefore, the lowest common multiple of 985,928,288,571 is 4697457120.
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.
985 x 928 x 288 x 571 = 150318627840
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.
985 : 1, 5, 197, 985
928 : 1, 2, 4, 8, 16, 29, 32, 58, 116, 232, 464, 928
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
571 : 1, 571
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 985,928,288,571, is 1.
Now, the common factors can be found like this.
985:5x 197
928:2x 2x 2x 2x 2x 29
288:2x 2x 2x 2x 2x 3x 3
571:571
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 2 = 32
Therefore, the value for common factors is 32.
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 = 150318627840/(1x32)
LCM = 150318627840/32
LCM = 4697457120
Thus, we can understand that the LCM of 985,928,288,571 is 4697457120.
