Given numbers are 394,897,368,402
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 394,897,368,402 is 189432048.
Find LCM of 394,897,368,402 with Prime Factorization
| 2 | 394, 897, 368, 402 |
| 3 | 197, 897, 184, 201 |
| 23 | 197, 299, 184, 67 |
| 197, 13, 8, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 197 x 13 x 8 x 67 = 189432048
Therefore, the lowest common multiple of 394,897,368,402 is 189432048.
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.
394 x 897 x 368 x 402 = 52283245248
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.
394 : 1, 2, 197, 394
897 : 1, 3, 13, 23, 39, 69, 299, 897
368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368
402 : 1, 2, 3, 6, 67, 134, 201, 402
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 394,897,368,402, is 1.
Now, the common factors can be found like this.
394:2x 197
897:3x 13x 23
368:2x 2x 2x 2x 23
402:2x 3x 67
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 23 = 276
Therefore, the value for common factors is 276.
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 = 52283245248/(1x276)
LCM = 52283245248/276
LCM = 189432048
Thus, we can understand that the LCM of 394,897,368,402 is 189432048.
