Given numbers are 483,447,640,638,836
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 483,447,640,638,836 is 279162871680.
Find LCM of 483,447,640,638,836 with Prime Factorization
| 2 | 483, 447, 640, 638, 836 |
| 2 | 483, 447, 320, 319, 418 |
| 3 | 483, 447, 160, 319, 209 |
| 11 | 161, 149, 160, 319, 209 |
| 161, 149, 160, 29, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 161 x 149 x 160 x 29 x 19 = 279162871680
Therefore, the lowest common multiple of 483,447,640,638,836 is 279162871680.
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.
483 x 447 x 640 x 638 x 836 = 73698998123520
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.
483 : 1, 3, 7, 21, 23, 69, 161, 483
447 : 1, 3, 149, 447
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
638 : 1, 2, 11, 22, 29, 58, 319, 638
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 483,447,640,638,836, is 1.
Now, the common factors can be found like this.
483:3x 7x 23
447:3x 149
640:2x 2x 2x 2x 2x 2x 2x 5
638:2x 11x 29
836:2x 2x 11x 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 3x 11 = 264
Therefore, the value for common factors is 264.
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 = 73698998123520/(1x264)
LCM = 73698998123520/264
LCM = 279162871680
Thus, we can understand that the LCM of 483,447,640,638,836 is 279162871680.
