Given numbers are 668,413,826,542
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 668,413,826,542 is 74764564.
Find LCM of 668,413,826,542 with Prime Factorization
| 2 | 668, 413, 826, 542 |
| 7 | 334, 413, 413, 271 |
| 59 | 334, 59, 59, 271 |
| 334, 1, 1, 271 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 59 x 334 x 1 x 1 x 271 = 74764564
Therefore, the lowest common multiple of 668,413,826,542 is 74764564.
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.
668 x 413 x 826 x 542 = 123511059728
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.
668 : 1, 2, 4, 167, 334, 668
413 : 1, 7, 59, 413
826 : 1, 2, 7, 14, 59, 118, 413, 826
542 : 1, 2, 271, 542
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,413,826,542, is 1.
Now, the common factors can be found like this.
668:2x 2x 167
413:7x 59
826:2x 7x 59
542:2x 271
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 7x 59 = 1652
Therefore, the value for common factors is 1652.
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 = 123511059728/(1x1652)
LCM = 123511059728/1652
LCM = 74764564
Thus, we can understand that the LCM of 668,413,826,542 is 74764564.
