Find LCM of 396,646,672,434,775 with Prime Factorization
| 2 | 396, 646, 672, 434, 775 |
| 2 | 198, 323, 336, 217, 775 |
| 3 | 99, 323, 168, 217, 775 |
| 7 | 33, 323, 56, 217, 775 |
| 31 | 33, 323, 8, 31, 775 |
| 33, 323, 8, 1, 25 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 31 x 33 x 323 x 8 x 1 x 25 = 5551207200
Therefore, the lowest common multiple of 396,646,672,434,775 is 5551207200.
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.
396 x 646 x 672 x 434 x 775 = 57821374195200
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.
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
646 : 1, 2, 17, 19, 34, 38, 323, 646
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
434 : 1, 2, 7, 14, 31, 62, 217, 434
775 : 1, 5, 25, 31, 155, 775
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 396,646,672,434,775, is 1.
Now, the common factors can be found like this.
396:2x 2x 3x 3x 11
646:2x 17x 19
672:2x 2x 2x 2x 2x 3x 7
434:2x 7x 31
775:5x 5x 31
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 3x 7x 31 = 10416
Therefore, the value for common factors is 10416.
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 = 57821374195200/(1x10416)
LCM = 57821374195200/10416
LCM = 5551207200
Thus, we can understand that the LCM of 396,646,672,434,775 is 5551207200.
