Given numbers are 858,611,845,747
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 858,611,845,747 is 652676310.
Find LCM of 858,611,845,747 with Prime Factorization
| 3 | 858, 611, 845, 747 |
| 13 | 286, 611, 845, 249 |
| 22, 47, 65, 249 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 22 x 47 x 65 x 249 = 652676310
Therefore, the lowest common multiple of 858,611,845,747 is 652676310.
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.
858 x 611 x 845 x 747 = 330906889170
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.
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
611 : 1, 13, 47, 611
845 : 1, 5, 13, 65, 169, 845
747 : 1, 3, 9, 83, 249, 747
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,611,845,747, is 1.
Now, the common factors can be found like this.
858:2x 3x 11x 13
611:13x 47
845:5x 13x 13
747:3x 3x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13x 13 = 507
Therefore, the value for common factors is 507.
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 = 330906889170/(1x507)
LCM = 330906889170/507
LCM = 652676310
Thus, we can understand that the LCM of 858,611,845,747 is 652676310.
