Given numbers are 643,152,818,627,437
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 643,152,818,627,437 is 30340284216.
Find LCM of 643,152,818,627,437 with Prime Factorization
| 2 | 643, 152, 818, 627, 437 |
| 19 | 643, 76, 409, 627, 437 |
| 643, 4, 409, 33, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 643 x 4 x 409 x 33 x 23 = 30340284216
Therefore, the lowest common multiple of 643,152,818,627,437 is 30340284216.
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 152 x 818 x 627 x 437 = 21905685203952
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
152 : 1, 2, 4, 8, 19, 38, 76, 152
818 : 1, 2, 409, 818
627 : 1, 3, 11, 19, 33, 57, 209, 627
437 : 1, 19, 23, 437
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,152,818,627,437, is 1.
Now, the common factors can be found like this.
643:643
152:2x 2x 2x 19
818:2x 409
627:3x 11x 19
437:19x 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 19x 19 = 722
Therefore, the value for common factors is 722.
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 = 21905685203952/(1x722)
LCM = 21905685203952/722
LCM = 30340284216
Thus, we can understand that the LCM of 643,152,818,627,437 is 30340284216.
