Given numbers are 811,420,198,337,121
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 811,420,198,337,121 is 41668385220.
Find LCM of 811,420,198,337,121 with Prime Factorization
| 2 | 811, 420, 198, 337, 121 |
| 3 | 811, 210, 99, 337, 121 |
| 11 | 811, 70, 33, 337, 121 |
| 811, 70, 3, 337, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 811 x 70 x 3 x 337 x 11 = 41668385220
Therefore, the lowest common multiple of 811,420,198,337,121 is 41668385220.
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.
811 x 420 x 198 x 337 x 121 = 2750113424520
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.
811 : 1, 811
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
337 : 1, 337
121 : 1, 11, 121
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 811,420,198,337,121, is 1.
Now, the common factors can be found like this.
811:811
420:2x 2x 3x 5x 7
198:2x 3x 3x 11
337:337
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 3x 11 = 66
Therefore, the value for common factors is 66.
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 = 2750113424520/(1x66)
LCM = 2750113424520/66
LCM = 41668385220
Thus, we can understand that the LCM of 811,420,198,337,121 is 41668385220.
