Given numbers are 461,516,561,643
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 461,516,561,643 is 28602448116.
Find LCM of 461,516,561,643 with Prime Factorization
| 3 | 461, 516, 561, 643 |
| 461, 172, 187, 643 |
Multiply the prime numbers at the bottom and the left side.
3 x 461 x 172 x 187 x 643 = 28602448116
Therefore, the lowest common multiple of 461,516,561,643 is 28602448116.
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.
461 x 516 x 561 x 643 = 85807344348
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.
461 : 1, 461
516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516
561 : 1, 3, 11, 17, 33, 51, 187, 561
643 : 1, 643
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 461,516,561,643, is 1.
Now, the common factors can be found like this.
461:461
516:2x 2x 3x 43
561:3x 11x 17
643:643
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 85807344348/(1x3)
LCM = 85807344348/3
LCM = 28602448116
Thus, we can understand that the LCM of 461,516,561,643 is 28602448116.
