Given numbers are 789,957,462,866,454
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 789,957,462,866,454 is 346345441134.
Find LCM of 789,957,462,866,454 with Prime Factorization
| 2 | 789, 957, 462, 866, 454 |
| 3 | 789, 957, 231, 433, 227 |
| 11 | 263, 319, 77, 433, 227 |
| 263, 29, 7, 433, 227 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 263 x 29 x 7 x 433 x 227 = 346345441134
Therefore, the lowest common multiple of 789,957,462,866,454 is 346345441134.
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.
789 x 957 x 462 x 866 x 454 = 137152794689064
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.
789 : 1, 3, 263, 789
957 : 1, 3, 11, 29, 33, 87, 319, 957
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
866 : 1, 2, 433, 866
454 : 1, 2, 227, 454
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 789,957,462,866,454, is 1.
Now, the common factors can be found like this.
789:3x 263
957:3x 11x 29
462:2x 3x 7x 11
866:2x 433
454:2x 227
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 11 = 396
Therefore, the value for common factors is 396.
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 = 137152794689064/(1x396)
LCM = 137152794689064/396
LCM = 346345441134
Thus, we can understand that the LCM of 789,957,462,866,454 is 346345441134.
