Given numbers are 642,542,618,879,586
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 642,542,618,879,586 is 5250602778.
Find LCM of 642,542,618,879,586 with Prime Factorization
| 2 | 642, 542, 618, 879, 586 |
| 3 | 321, 271, 309, 879, 293 |
| 293 | 107, 271, 103, 293, 293 |
| 107, 271, 103, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 293 x 107 x 271 x 103 x 1 x 1 = 5250602778
Therefore, the lowest common multiple of 642,542,618,879,586 is 5250602778.
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.
642 x 542 x 618 x 879 x 586 = 110766716204688
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.
642 : 1, 2, 3, 6, 107, 214, 321, 642
542 : 1, 2, 271, 542
618 : 1, 2, 3, 6, 103, 206, 309, 618
879 : 1, 3, 293, 879
586 : 1, 2, 293, 586
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,542,618,879,586, is 1.
Now, the common factors can be found like this.
642:2x 3x 107
542:2x 271
618:2x 3x 103
879:3x 293
586:2x 293
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 2x 3x 3x 293 = 21096
Therefore, the value for common factors is 21096.
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 = 110766716204688/(1x21096)
LCM = 110766716204688/21096
LCM = 5250602778
Thus, we can understand that the LCM of 642,542,618,879,586 is 5250602778.
