Given numbers are 561,303,498,384,428
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,303,498,384,428 is 64410411648.
Find LCM of 561,303,498,384,428 with Prime Factorization
| 2 | 561, 303, 498, 384, 428 |
| 2 | 561, 303, 249, 192, 214 |
| 3 | 561, 303, 249, 96, 107 |
| 187, 101, 83, 32, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 187 x 101 x 83 x 32 x 107 = 64410411648
Therefore, the lowest common multiple of 561,303,498,384,428 is 64410411648.
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.
561 x 303 x 498 x 384 x 428 = 13912648915968
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
303 : 1, 3, 101, 303
498 : 1, 2, 3, 6, 83, 166, 249, 498
384 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 384
428 : 1, 2, 4, 107, 214, 428
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,303,498,384,428, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
303:3x 101
498:2x 3x 83
384:2x 2x 2x 2x 2x 2x 2x 3
428:2x 2x 107
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 = 13912648915968/(1x216)
LCM = 13912648915968/216
LCM = 64410411648
Thus, we can understand that the LCM of 561,303,498,384,428 is 64410411648.
