Given numbers are 643,656,789,614
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 643,656,789,614 is 102171599184.
Find LCM of 643,656,789,614 with Prime Factorization
| 2 | 643, 656, 789, 614 |
| 643, 328, 789, 307 |
Multiply the prime numbers at the bottom and the left side.
2 x 643 x 328 x 789 x 307 = 102171599184
Therefore, the lowest common multiple of 643,656,789,614 is 102171599184.
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.
643 x 656 x 789 x 614 = 204343198368
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.
643 : 1, 643
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
789 : 1, 3, 263, 789
614 : 1, 2, 307, 614
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,656,789,614, is 1.
Now, the common factors can be found like this.
643:643
656:2x 2x 2x 2x 41
789:3x 263
614:2x 307
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 204343198368/(1x2)
LCM = 204343198368/2
LCM = 102171599184
Thus, we can understand that the LCM of 643,656,789,614 is 102171599184.
