Given numbers are 648,417,981,528
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 648,417,981,528 is 215992656.
Find LCM of 648,417,981,528 with Prime Factorization
| 2 | 648, 417, 981, 528 |
| 2 | 324, 417, 981, 264 |
| 2 | 162, 417, 981, 132 |
| 3 | 81, 417, 981, 66 |
| 3 | 27, 139, 327, 22 |
| 9, 139, 109, 22 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 9 x 139 x 109 x 22 = 215992656
Therefore, the lowest common multiple of 648,417,981,528 is 215992656.
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.
648 x 417 x 981 x 528 = 139963241088
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.
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
417 : 1, 3, 139, 417
981 : 1, 3, 9, 109, 327, 981
528 : 1, 2, 3, 4, 6, 8, 11, 12, 16, 22, 24, 33, 44, 48, 66, 88, 132, 176, 264, 528
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 648,417,981,528, is 3.
Now, the common factors can be found like this.
648:2x 2x 2x 3x 3x 3x 3
417:3x 139
981:3x 3x 109
528:2x 2x 2x 2x 3x 11
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 3x 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 139963241088/(3x216)
LCM = 139963241088/648
LCM = 215992656
Thus, we can understand that the LCM of 648,417,981,528 is 215992656.
