Given numbers are 396,547,605,565,641
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 396,547,605,565,641 is 862942134780.
Find LCM of 396,547,605,565,641 with Prime Factorization
| 5 | 396, 547, 605, 565, 641 |
| 11 | 396, 547, 121, 113, 641 |
| 36, 547, 11, 113, 641 |
Multiply the prime numbers at the bottom and the left side.
5 x 11 x 36 x 547 x 11 x 113 x 641 = 862942134780
Therefore, the lowest common multiple of 396,547,605,565,641 is 862942134780.
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.
396 x 547 x 605 x 565 x 641 = 47461817412900
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.
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
547 : 1, 547
605 : 1, 5, 11, 55, 121, 605
565 : 1, 5, 113, 565
641 : 1, 641
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 396,547,605,565,641, is 1.
Now, the common factors can be found like this.
396:2x 2x 3x 3x 11
547:547
605:5x 11x 11
565:5x 113
641:641
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 11 = 55
Therefore, the value for common factors is 55.
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 = 47461817412900/(1x55)
LCM = 47461817412900/55
LCM = 862942134780
Thus, we can understand that the LCM of 396,547,605,565,641 is 862942134780.
