Given numbers are 451,627,686,656
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 451,627,686,656 is 141080016.
Find LCM of 451,627,686,656 with Prime Factorization
| 2 | 451, 627, 686, 656 |
| 11 | 451, 627, 343, 328 |
| 41 | 41, 57, 343, 328 |
| 1, 57, 343, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 41 x 1 x 57 x 343 x 8 = 141080016
Therefore, the lowest common multiple of 451,627,686,656 is 141080016.
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.
451 x 627 x 686 x 656 = 127254174432
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.
451 : 1, 11, 41, 451
627 : 1, 3, 11, 19, 33, 57, 209, 627
686 : 1, 2, 7, 14, 49, 98, 343, 686
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 451,627,686,656, is 1.
Now, the common factors can be found like this.
451:11x 41
627:3x 11x 19
686:2x 7x 7x 7
656:2x 2x 2x 2x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 41 = 902
Therefore, the value for common factors is 902.
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 = 127254174432/(1x902)
LCM = 127254174432/902
LCM = 141080016
Thus, we can understand that the LCM of 451,627,686,656 is 141080016.
