The LCM of 449,960,780,663 is 95259840.
Find LCM of 449,960,780,663 with Prime Factorization
| 2 | 449, 960, 780, 663 |
| 2 | 449, 480, 390, 663 |
| 3 | 449, 240, 195, 663 |
| 5 | 449, 80, 65, 221 |
| 13 | 449, 16, 13, 221 |
| 449, 16, 1, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 449 x 16 x 1 x 17 = 95259840
Therefore, the lowest common multiple of 449,960,780,663 is 95259840.
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.
449 x 960 x 780 x 663 = 222908025600
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.
449 : 1, 449
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
663 : 1, 3, 13, 17, 39, 51, 221, 663
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 449,960,780,663, is 1.
Now, the common factors can be found like this.
449:449
960:2x 2x 2x 2x 2x 2x 3x 5
780:2x 2x 3x 5x 13
663:3x 13x 17
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 5x 13 = 2340
Therefore, the value for common factors is 2340.
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 = 222908025600/(1x2340)
LCM = 222908025600/2340
LCM = 95259840
Thus, we can understand that the LCM of 449,960,780,663 is 95259840.
