Given numbers are 804,647,156,776,621
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 804,647,156,776,621 is 271566226152.
Find LCM of 804,647,156,776,621 with Prime Factorization
| 2 | 804, 647, 156, 776, 621 |
| 2 | 402, 647, 78, 388, 621 |
| 3 | 201, 647, 39, 194, 621 |
| 67, 647, 13, 194, 207 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 67 x 647 x 13 x 194 x 207 = 271566226152
Therefore, the lowest common multiple of 804,647,156,776,621 is 271566226152.
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.
804 x 647 x 156 x 776 x 621 = 39105536565888
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.
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
647 : 1, 647
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
776 : 1, 2, 4, 8, 97, 194, 388, 776
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 804,647,156,776,621, is 1.
Now, the common factors can be found like this.
804:2x 2x 3x 67
647:647
156:2x 2x 3x 13
776:2x 2x 2x 97
621:3x 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 2x 2x 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 39105536565888/(1x144)
LCM = 39105536565888/144
LCM = 271566226152
Thus, we can understand that the LCM of 804,647,156,776,621 is 271566226152.
