Given numbers are 646,333,221,466,766
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 646,333,221,466,766 is 249559897626.
Find LCM of 646,333,221,466,766 with Prime Factorization
| 2 | 646, 333, 221, 466, 766 |
| 17 | 323, 333, 221, 233, 383 |
| 19, 333, 13, 233, 383 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 19 x 333 x 13 x 233 x 383 = 249559897626
Therefore, the lowest common multiple of 646,333,221,466,766 is 249559897626.
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.
646 x 333 x 221 x 466 x 766 = 16970073038568
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
333 : 1, 3, 9, 37, 111, 333
221 : 1, 13, 17, 221
466 : 1, 2, 233, 466
766 : 1, 2, 383, 766
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,333,221,466,766, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
333:3x 3x 37
221:13x 17
466:2x 233
766:2x 383
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 17 = 68
Therefore, the value for common factors is 68.
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 = 16970073038568/(1x68)
LCM = 16970073038568/68
LCM = 249559897626
Thus, we can understand that the LCM of 646,333,221,466,766 is 249559897626.
