Given numbers are 330,736,640,914
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 330,736,640,914 is 221992320.
Find LCM of 330,736,640,914 with Prime Factorization
| 2 | 330, 736, 640, 914 |
| 2 | 165, 368, 320, 457 |
| 2 | 165, 184, 160, 457 |
| 2 | 165, 92, 80, 457 |
| 2 | 165, 46, 40, 457 |
| 5 | 165, 23, 20, 457 |
| 33, 23, 4, 457 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 5 x 33 x 23 x 4 x 457 = 221992320
Therefore, the lowest common multiple of 330,736,640,914 is 221992320.
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 736 x 640 x 914 = 142075084800
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
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
914 : 1, 2, 457, 914
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 330,736,640,914, is 2.
Now, the common factors can be found like this.
330:2x 3x 5x 11
736:2x 2x 2x 2x 2x 23
640:2x 2x 2x 2x 2x 2x 2x 5
914:2x 457
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 2x 5 = 320
Therefore, the value for common factors is 320.
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 = 142075084800/(2x320)
LCM = 142075084800/640
LCM = 221992320
Thus, we can understand that the LCM of 330,736,640,914 is 221992320.
