Given numbers are 478,649,906,828
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 478,649,906,828 is 19393218108.
Find LCM of 478,649,906,828 with Prime Factorization
| 2 | 478, 649, 906, 828 |
| 3 | 239, 649, 453, 414 |
| 239, 649, 151, 138 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 239 x 649 x 151 x 138 = 19393218108
Therefore, the lowest common multiple of 478,649,906,828 is 19393218108.
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 649 x 906 x 828 = 232718617296
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
649 : 1, 11, 59, 649
906 : 1, 2, 3, 6, 151, 302, 453, 906
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,649,906,828, is 1.
Now, the common factors can be found like this.
478:2x 239
649:11x 59
906:2x 3x 151
828:2x 2x 3x 3x 23
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 3 = 12
Therefore, the value for common factors is 12.
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 = 232718617296/(1x12)
LCM = 232718617296/12
LCM = 19393218108
Thus, we can understand that the LCM of 478,649,906,828 is 19393218108.
