Given numbers are 813,894,805,894
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 813,894,805,894 is 195030570.
Find LCM of 813,894,805,894 with Prime Factorization
| 2 | 813, 894, 805, 894 |
| 3 | 813, 447, 805, 447 |
| 149 | 271, 149, 805, 149 |
| 271, 1, 805, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 149 x 271 x 1 x 805 x 1 = 195030570
Therefore, the lowest common multiple of 813,894,805,894 is 195030570.
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.
813 x 894 x 805 x 894 = 523071988740
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.
813 : 1, 3, 271, 813
894 : 1, 2, 3, 6, 149, 298, 447, 894
805 : 1, 5, 7, 23, 35, 115, 161, 805
894 : 1, 2, 3, 6, 149, 298, 447, 894
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,894,805,894, is 1.
Now, the common factors can be found like this.
813:3x 271
894:2x 3x 149
805:5x 7x 23
894:2x 3x 149
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 149 = 2682
Therefore, the value for common factors is 2682.
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 = 523071988740/(1x2682)
LCM = 523071988740/2682
LCM = 195030570
Thus, we can understand that the LCM of 813,894,805,894 is 195030570.
