Given numbers are 911,836,981,638,284
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 911,836,981,638,284 is 1538331766884.
Find LCM of 911,836,981,638,284 with Prime Factorization
| 2 | 911, 836, 981, 638, 284 |
| 2 | 911, 418, 981, 319, 142 |
| 11 | 911, 209, 981, 319, 71 |
| 911, 19, 981, 29, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 911 x 19 x 981 x 29 x 71 = 1538331766884
Therefore, the lowest common multiple of 911,836,981,638,284 is 1538331766884.
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.
911 x 836 x 981 x 638 x 284 = 135373195485792
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.
911 : 1, 911
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
981 : 1, 3, 9, 109, 327, 981
638 : 1, 2, 11, 22, 29, 58, 319, 638
284 : 1, 2, 4, 71, 142, 284
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 911,836,981,638,284, is 1.
Now, the common factors can be found like this.
911:911
836:2x 2x 11x 19
981:3x 3x 109
638:2x 11x 29
284:2x 2x 71
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 11 = 88
Therefore, the value for common factors is 88.
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 = 135373195485792/(1x88)
LCM = 135373195485792/88
LCM = 1538331766884
Thus, we can understand that the LCM of 911,836,981,638,284 is 1538331766884.
