Given numbers are 447,846,846,778
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 447,846,846,778 is 49035006.
Find LCM of 447,846,846,778 with Prime Factorization
| 2 | 447, 846, 846, 778 |
| 3 | 447, 423, 423, 389 |
| 3 | 149, 141, 141, 389 |
| 47 | 149, 47, 47, 389 |
| 149, 1, 1, 389 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 47 x 149 x 1 x 1 x 389 = 49035006
Therefore, the lowest common multiple of 447,846,846,778 is 49035006.
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.
447 x 846 x 846 x 778 = 248901690456
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.
447 : 1, 3, 149, 447
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
778 : 1, 2, 389, 778
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 447,846,846,778, is 1.
Now, the common factors can be found like this.
447:3x 149
846:2x 3x 3x 47
846:2x 3x 3x 47
778:2x 389
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 47 = 5076
Therefore, the value for common factors is 5076.
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 = 248901690456/(1x5076)
LCM = 248901690456/5076
LCM = 49035006
Thus, we can understand that the LCM of 447,846,846,778 is 49035006.
