Find LCM of 388,985,522,700,287 with Prime Factorization
| 2 | 388, 985, 522, 700, 287 |
| 2 | 194, 985, 261, 350, 287 |
| 5 | 97, 985, 261, 175, 287 |
| 7 | 97, 197, 261, 35, 287 |
| 97, 197, 261, 5, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 97 x 197 x 261 x 5 x 41 = 143139786300
Therefore, the lowest common multiple of 388,985,522,700,287 is 143139786300.
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.
388 x 985 x 522 x 700 x 287 = 40079140164000
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.
388 : 1, 2, 4, 97, 194, 388
985 : 1, 5, 197, 985
522 : 1, 2, 3, 6, 9, 18, 29, 58, 87, 174, 261, 522
700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
287 : 1, 7, 41, 287
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,985,522,700,287, is 1.
Now, the common factors can be found like this.
388:2x 2x 97
985:5x 197
522:2x 3x 3x 29
700:2x 2x 5x 5x 7
287:7x 41
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 5x 7 = 280
Therefore, the value for common factors is 280.
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 = 40079140164000/(1x280)
LCM = 40079140164000/280
LCM = 143139786300
Thus, we can understand that the LCM of 388,985,522,700,287 is 143139786300.
