Given numbers are 511,398,418,731,121
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 511,398,418,731,121 is 341790762082.
Find LCM of 511,398,418,731,121 with Prime Factorization
| 2 | 511, 398, 418, 731, 121 |
| 11 | 511, 199, 209, 731, 121 |
| 511, 199, 19, 731, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 511 x 199 x 19 x 731 x 11 = 341790762082
Therefore, the lowest common multiple of 511,398,418,731,121 is 341790762082.
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.
511 x 398 x 418 x 731 x 121 = 7519396765804
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.
511 : 1, 7, 73, 511
398 : 1, 2, 199, 398
418 : 1, 2, 11, 19, 22, 38, 209, 418
731 : 1, 17, 43, 731
121 : 1, 11, 121
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 511,398,418,731,121, is 1.
Now, the common factors can be found like this.
511:7x 73
398:2x 199
418:2x 11x 19
731:17x 43
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 11 = 22
Therefore, the value for common factors is 22.
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 = 7519396765804/(1x22)
LCM = 7519396765804/22
LCM = 341790762082
Thus, we can understand that the LCM of 511,398,418,731,121 is 341790762082.
