Find LCM of 640,207,999,499,481 with Prime Factorization
| 3 | 640, 207, 999, 499, 481 |
| 3 | 640, 69, 333, 499, 481 |
| 37 | 640, 23, 111, 499, 481 |
| 640, 23, 3, 499, 13 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 37 x 640 x 23 x 3 x 499 x 13 = 95393151360
Therefore, the lowest common multiple of 640,207,999,499,481 is 95393151360.
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.
640 x 207 x 999 x 499 x 481 = 31765919402880
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.
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
207 : 1, 3, 9, 23, 69, 207
999 : 1, 3, 9, 27, 37, 111, 333, 999
499 : 1, 499
481 : 1, 13, 37, 481
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,207,999,499,481, is 1.
Now, the common factors can be found like this.
640:2x 2x 2x 2x 2x 2x 2x 5
207:3x 3x 23
999:3x 3x 3x 37
499:499
481:13x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 37 = 333
Therefore, the value for common factors is 333.
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 = 31765919402880/(1x333)
LCM = 31765919402880/333
LCM = 95393151360
Thus, we can understand that the LCM of 640,207,999,499,481 is 95393151360.
