Given numbers are 486,418,776,646,415
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 486,418,776,646,415 is 278042573160.
Find LCM of 486,418,776,646,415 with Prime Factorization
| 2 | 486, 418, 776, 646, 415 |
| 19 | 243, 209, 388, 323, 415 |
| 243, 11, 388, 17, 415 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 243 x 11 x 388 x 17 x 415 = 278042573160
Therefore, the lowest common multiple of 486,418,776,646,415 is 278042573160.
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.
486 x 418 x 776 x 646 x 415 = 42262471120320
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.
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
418 : 1, 2, 11, 19, 22, 38, 209, 418
776 : 1, 2, 4, 8, 97, 194, 388, 776
646 : 1, 2, 17, 19, 34, 38, 323, 646
415 : 1, 5, 83, 415
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 486,418,776,646,415, is 1.
Now, the common factors can be found like this.
486:2x 3x 3x 3x 3x 3
418:2x 11x 19
776:2x 2x 2x 97
646:2x 17x 19
415:5x 83
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 19 = 152
Therefore, the value for common factors is 152.
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 = 42262471120320/(1x152)
LCM = 42262471120320/152
LCM = 278042573160
Thus, we can understand that the LCM of 486,418,776,646,415 is 278042573160.
