Given numbers are 481,648,145,487,728
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 481,648,145,487,728 is 154068936840.
Find LCM of 481,648,145,487,728 with Prime Factorization
| 2 | 481, 648, 145, 487, 728 |
| 2 | 481, 324, 145, 487, 364 |
| 2 | 481, 162, 145, 487, 182 |
| 13 | 481, 81, 145, 487, 91 |
| 37, 81, 145, 487, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 13 x 37 x 81 x 145 x 487 x 7 = 154068936840
Therefore, the lowest common multiple of 481,648,145,487,728 is 154068936840.
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.
481 x 648 x 145 x 487 x 728 = 16023169431360
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.
481 : 1, 13, 37, 481
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
145 : 1, 5, 29, 145
487 : 1, 487
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 481,648,145,487,728, is 1.
Now, the common factors can be found like this.
481:13x 37
648:2x 2x 2x 3x 3x 3x 3
145:5x 29
487:487
728:2x 2x 2x 7x 13
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 13 = 104
Therefore, the value for common factors is 104.
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 = 16023169431360/(1x104)
LCM = 16023169431360/104
LCM = 154068936840
Thus, we can understand that the LCM of 481,648,145,487,728 is 154068936840.
