Given numbers are 330,763,646,387,648
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 330,763,646,387,648 is 377688021480.
Find LCM of 330,763,646,387,648 with Prime Factorization
| 2 | 330, 763, 646, 387, 648 |
| 3 | 165, 763, 323, 387, 324 |
| 3 | 55, 763, 323, 129, 108 |
| 55, 763, 323, 43, 36 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 55 x 763 x 323 x 43 x 36 = 377688021480
Therefore, the lowest common multiple of 330,763,646,387,648 is 377688021480.
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 763 x 646 x 387 x 648 = 40790306319840
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
763 : 1, 7, 109, 763
646 : 1, 2, 17, 19, 34, 38, 323, 646
387 : 1, 3, 9, 43, 129, 387
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 330,763,646,387,648, is 1.
Now, the common factors can be found like this.
330:2x 3x 5x 11
763:7x 109
646:2x 17x 19
387:3x 3x 43
648:2x 2x 2x 3x 3x 3x 3
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 3x 3x 3 = 108
Therefore, the value for common factors is 108.
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 = 40790306319840/(1x108)
LCM = 40790306319840/108
LCM = 377688021480
Thus, we can understand that the LCM of 330,763,646,387,648 is 377688021480.
