Given numbers are 845,850,857,646
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 845,850,857,646 is 2339052950.
Find LCM of 845,850,857,646 with Prime Factorization
| 2 | 845, 850, 857, 646 |
| 5 | 845, 425, 857, 323 |
| 17 | 169, 85, 857, 323 |
| 169, 5, 857, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 169 x 5 x 857 x 19 = 2339052950
Therefore, the lowest common multiple of 845,850,857,646 is 2339052950.
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.
845 x 850 x 857 x 646 = 397639001500
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.
845 : 1, 5, 13, 65, 169, 845
850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850
857 : 1, 857
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,850,857,646, is 1.
Now, the common factors can be found like this.
845:5x 13x 13
850:2x 5x 5x 17
857:857
646:2x 17x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 17 = 170
Therefore, the value for common factors is 170.
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 = 397639001500/(1x170)
LCM = 397639001500/170
LCM = 2339052950
Thus, we can understand that the LCM of 845,850,857,646 is 2339052950.
