Given numbers are 843,800,836,724,121
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 843,800,836,724,121 is 280630653600.
Find LCM of 843,800,836,724,121 with Prime Factorization
| 2 | 843, 800, 836, 724, 121 |
| 2 | 843, 400, 418, 362, 121 |
| 11 | 843, 200, 209, 181, 121 |
| 843, 200, 19, 181, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 843 x 200 x 19 x 181 x 11 = 280630653600
Therefore, the lowest common multiple of 843,800,836,724,121 is 280630653600.
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.
843 x 800 x 836 x 724 x 121 = 49390995033600
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.
843 : 1, 3, 281, 843
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
724 : 1, 2, 4, 181, 362, 724
121 : 1, 11, 121
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 843,800,836,724,121, is 1.
Now, the common factors can be found like this.
843:3x 281
800:2x 2x 2x 2x 2x 5x 5
836:2x 2x 11x 19
724:2x 2x 181
121:11x 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 2x 2x 11 = 176
Therefore, the value for common factors is 176.
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 = 49390995033600/(1x176)
LCM = 49390995033600/176
LCM = 280630653600
Thus, we can understand that the LCM of 843,800,836,724,121 is 280630653600.
