Given numbers are 923,306,781,851,806
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 923,306,781,851,806 is 81960965658.
Find LCM of 923,306,781,851,806 with Prime Factorization
| 2 | 923, 306, 781, 851, 806 |
| 13 | 923, 153, 781, 851, 403 |
| 71 | 71, 153, 781, 851, 31 |
| 1, 153, 11, 851, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 71 x 1 x 153 x 11 x 851 x 31 = 81960965658
Therefore, the lowest common multiple of 923,306,781,851,806 is 81960965658.
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.
923 x 306 x 781 x 851 x 806 = 151299942604668
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.
923 : 1, 13, 71, 923
306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306
781 : 1, 11, 71, 781
851 : 1, 23, 37, 851
806 : 1, 2, 13, 26, 31, 62, 403, 806
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 923,306,781,851,806, is 1.
Now, the common factors can be found like this.
923:13x 71
306:2x 3x 3x 17
781:11x 71
851:23x 37
806:2x 13x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 71 = 1846
Therefore, the value for common factors is 1846.
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 = 151299942604668/(1x1846)
LCM = 151299942604668/1846
LCM = 81960965658
Thus, we can understand that the LCM of 923,306,781,851,806 is 81960965658.
