Given numbers are 478,381,168,381
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 478,381,168,381 is 5099304.
Find LCM of 478,381,168,381 with Prime Factorization
| 2 | 478, 381, 168, 381 |
| 3 | 239, 381, 84, 381 |
| 127 | 239, 127, 28, 127 |
| 239, 1, 28, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 127 x 239 x 1 x 28 x 1 = 5099304
Therefore, the lowest common multiple of 478,381,168,381 is 5099304.
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.
478 x 381 x 168 x 381 = 11657008944
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.
478 : 1, 2, 239, 478
381 : 1, 3, 127, 381
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
381 : 1, 3, 127, 381
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,381,168,381, is 1.
Now, the common factors can be found like this.
478:2x 239
381:3x 127
168:2x 2x 2x 3x 7
381:3x 127
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 127 = 2286
Therefore, the value for common factors is 2286.
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 = 11657008944/(1x2286)
LCM = 11657008944/2286
LCM = 5099304
Thus, we can understand that the LCM of 478,381,168,381 is 5099304.
