Given numbers are 812,867,993,789,440
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 812,867,993,789,440 is 6741422623320.
Find LCM of 812,867,993,789,440 with Prime Factorization
| 2 | 812, 867, 993, 789, 440 |
| 2 | 406, 867, 993, 789, 220 |
| 3 | 203, 867, 993, 789, 110 |
| 203, 289, 331, 263, 110 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 203 x 289 x 331 x 263 x 110 = 6741422623320
Therefore, the lowest common multiple of 812,867,993,789,440 is 6741422623320.
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.
812 x 867 x 993 x 789 x 440 = 242691214439520
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.
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
867 : 1, 3, 17, 51, 289, 867
993 : 1, 3, 331, 993
789 : 1, 3, 263, 789
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 812,867,993,789,440, is 1.
Now, the common factors can be found like this.
812:2x 2x 7x 29
867:3x 17x 17
993:3x 331
789:3x 263
440:2x 2x 2x 5x 11
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 3x 3 = 36
Therefore, the value for common factors is 36.
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 = 242691214439520/(1x36)
LCM = 242691214439520/36
LCM = 6741422623320
Thus, we can understand that the LCM of 812,867,993,789,440 is 6741422623320.
