Given numbers are 418,921,926,703,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 418,921,926,703,638 is 191256685422.
Find LCM of 418,921,926,703,638 with Prime Factorization
| 2 | 418, 921, 926, 703, 638 |
| 11 | 209, 921, 463, 703, 319 |
| 19 | 19, 921, 463, 703, 29 |
| 1, 921, 463, 37, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 19 x 1 x 921 x 463 x 37 x 29 = 191256685422
Therefore, the lowest common multiple of 418,921,926,703,638 is 191256685422.
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.
418 x 921 x 926 x 703 x 638 = 159890589012792
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.
418 : 1, 2, 11, 19, 22, 38, 209, 418
921 : 1, 3, 307, 921
926 : 1, 2, 463, 926
703 : 1, 19, 37, 703
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,921,926,703,638, is 1.
Now, the common factors can be found like this.
418:2x 11x 19
921:3x 307
926:2x 463
703:19x 37
638:2x 11x 29
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 11x 19 = 836
Therefore, the value for common factors is 836.
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 = 159890589012792/(1x836)
LCM = 159890589012792/836
LCM = 191256685422
Thus, we can understand that the LCM of 418,921,926,703,638 is 191256685422.
