Given numbers are 211,287,494,418,421
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 211,287,494,418,421 is 138537096698.
Find LCM of 211,287,494,418,421 with Prime Factorization
| 2 | 211, 287, 494, 418, 421 |
| 19 | 211, 287, 247, 209, 421 |
| 211, 287, 13, 11, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 211 x 287 x 13 x 11 x 421 = 138537096698
Therefore, the lowest common multiple of 211,287,494,418,421 is 138537096698.
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.
211 x 287 x 494 x 418 x 421 = 5264409674524
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.
211 : 1, 211
287 : 1, 7, 41, 287
494 : 1, 2, 13, 19, 26, 38, 247, 494
418 : 1, 2, 11, 19, 22, 38, 209, 418
421 : 1, 421
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 211,287,494,418,421, is 1.
Now, the common factors can be found like this.
211:211
287:7x 41
494:2x 13x 19
418:2x 11x 19
421:421
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 19 = 38
Therefore, the value for common factors is 38.
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 = 5264409674524/(1x38)
LCM = 5264409674524/38
LCM = 138537096698
Thus, we can understand that the LCM of 211,287,494,418,421 is 138537096698.
