Given numbers are 396,653,102,428,780
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 396,653,102,428,780 is 30574152180.
Find LCM of 396,653,102,428,780 with Prime Factorization
| 2 | 396, 653, 102, 428, 780 |
| 2 | 198, 653, 51, 214, 390 |
| 3 | 99, 653, 51, 107, 195 |
| 33, 653, 17, 107, 65 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 33 x 653 x 17 x 107 x 65 = 30574152180
Therefore, the lowest common multiple of 396,653,102,428,780 is 30574152180.
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.
396 x 653 x 102 x 428 x 780 = 8805355827840
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.
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
653 : 1, 653
102 : 1, 2, 3, 6, 17, 34, 51, 102
428 : 1, 2, 4, 107, 214, 428
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 396,653,102,428,780, is 1.
Now, the common factors can be found like this.
396:2x 2x 3x 3x 11
653:653
102:2x 3x 17
428:2x 2x 107
780:2x 2x 3x 5x 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 2x 2x 3x 3 = 288
Therefore, the value for common factors is 288.
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 = 8805355827840/(1x288)
LCM = 8805355827840/288
LCM = 30574152180
Thus, we can understand that the LCM of 396,653,102,428,780 is 30574152180.
