Given numbers are 474,138,419,552,789
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 474,138,419,552,789 is 4805470776.
Find LCM of 474,138,419,552,789 with Prime Factorization
| 2 | 474, 138, 419, 552, 789 |
| 3 | 237, 69, 419, 276, 789 |
| 23 | 79, 23, 419, 92, 263 |
| 79, 1, 419, 4, 263 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 79 x 1 x 419 x 4 x 263 = 4805470776
Therefore, the lowest common multiple of 474,138,419,552,789 is 4805470776.
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.
474 x 138 x 419 x 552 x 789 = 11936789407584
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.
474 : 1, 2, 3, 6, 79, 158, 237, 474
138 : 1, 2, 3, 6, 23, 46, 69, 138
419 : 1, 419
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
789 : 1, 3, 263, 789
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 474,138,419,552,789, is 1.
Now, the common factors can be found like this.
474:2x 3x 79
138:2x 3x 23
419:419
552:2x 2x 2x 3x 23
789:3x 263
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 3x 23 = 2484
Therefore, the value for common factors is 2484.
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 = 11936789407584/(1x2484)
LCM = 11936789407584/2484
LCM = 4805470776
Thus, we can understand that the LCM of 474,138,419,552,789 is 4805470776.
