Given numbers are 851,645,418,682,634
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 851,645,418,682,634 is 2254688306970.
Find LCM of 851,645,418,682,634 with Prime Factorization
| 2 | 851, 645, 418, 682, 634 |
| 11 | 851, 645, 209, 341, 317 |
| 851, 645, 19, 31, 317 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 851 x 645 x 19 x 31 x 317 = 2254688306970
Therefore, the lowest common multiple of 851,645,418,682,634 is 2254688306970.
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.
851 x 645 x 418 x 682 x 634 = 99206285506680
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.
851 : 1, 23, 37, 851
645 : 1, 3, 5, 15, 43, 129, 215, 645
418 : 1, 2, 11, 19, 22, 38, 209, 418
682 : 1, 2, 11, 22, 31, 62, 341, 682
634 : 1, 2, 317, 634
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 851,645,418,682,634, is 1.
Now, the common factors can be found like this.
851:23x 37
645:3x 5x 43
418:2x 11x 19
682:2x 11x 31
634:2x 317
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 11 = 44
Therefore, the value for common factors is 44.
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 = 99206285506680/(1x44)
LCM = 99206285506680/44
LCM = 2254688306970
Thus, we can understand that the LCM of 851,645,418,682,634 is 2254688306970.
