Given numbers are 558,643,407,454
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 558,643,407,454 is 33148618866.
Find LCM of 558,643,407,454 with Prime Factorization
| 2 | 558, 643, 407, 454 |
| 279, 643, 407, 227 |
Multiply the prime numbers at the bottom and the left side.
2 x 279 x 643 x 407 x 227 = 33148618866
Therefore, the lowest common multiple of 558,643,407,454 is 33148618866.
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.
558 x 643 x 407 x 454 = 66297237732
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.
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
643 : 1, 643
407 : 1, 11, 37, 407
454 : 1, 2, 227, 454
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 558,643,407,454, is 1.
Now, the common factors can be found like this.
558:2x 3x 3x 31
643:643
407:11x 37
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.
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 = 66297237732/(1x2)
LCM = 66297237732/2
LCM = 33148618866
Thus, we can understand that the LCM of 558,643,407,454 is 33148618866.
