Given numbers are 665,634,566,382,817
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 665,634,566,382,817 is 979939269190.
Find LCM of 665,634,566,382,817 with Prime Factorization
| 2 | 665, 634, 566, 382, 817 |
| 19 | 665, 317, 283, 191, 817 |
| 35, 317, 283, 191, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 35 x 317 x 283 x 191 x 43 = 979939269190
Therefore, the lowest common multiple of 665,634,566,382,817 is 979939269190.
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.
665 x 634 x 566 x 382 x 817 = 74475384458440
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.
665 : 1, 5, 7, 19, 35, 95, 133, 665
634 : 1, 2, 317, 634
566 : 1, 2, 283, 566
382 : 1, 2, 191, 382
817 : 1, 19, 43, 817
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,634,566,382,817, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
634:2x 317
566:2x 283
382:2x 191
817:19x 43
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 19 = 76
Therefore, the value for common factors is 76.
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 = 74475384458440/(1x76)
LCM = 74475384458440/76
LCM = 979939269190
Thus, we can understand that the LCM of 665,634,566,382,817 is 979939269190.
