Given numbers are 330,476,685,818,646
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 330,476,685,818,646 is 83615804580.
Find LCM of 330,476,685,818,646 with Prime Factorization
| 2 | 330, 476, 685, 818, 646 |
| 5 | 165, 238, 685, 409, 323 |
| 17 | 33, 238, 137, 409, 323 |
| 33, 14, 137, 409, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 33 x 14 x 137 x 409 x 19 = 83615804580
Therefore, the lowest common multiple of 330,476,685,818,646 is 83615804580.
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.
330 x 476 x 685 x 818 x 646 = 56858747114400
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.
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
685 : 1, 5, 137, 685
818 : 1, 2, 409, 818
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 330,476,685,818,646, is 1.
Now, the common factors can be found like this.
330:2x 3x 5x 11
476:2x 2x 7x 17
685:5x 137
818:2x 409
646:2x 17x 19
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 5x 17 = 680
Therefore, the value for common factors is 680.
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 = 56858747114400/(1x680)
LCM = 56858747114400/680
LCM = 83615804580
Thus, we can understand that the LCM of 330,476,685,818,646 is 83615804580.
