Given numbers are 911,858,407,772,808
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 911,858,407,772,808 is 2254997491032.
Find LCM of 911,858,407,772,808 with Prime Factorization
| 2 | 911, 858, 407, 772, 808 |
| 2 | 911, 429, 407, 386, 404 |
| 11 | 911, 429, 407, 193, 202 |
| 911, 39, 37, 193, 202 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 911 x 39 x 37 x 193 x 202 = 2254997491032
Therefore, the lowest common multiple of 911,858,407,772,808 is 2254997491032.
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 858 x 407 x 772 x 808 = 198439779210816
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
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
407 : 1, 11, 37, 407
772 : 1, 2, 4, 193, 386, 772
808 : 1, 2, 4, 8, 101, 202, 404, 808
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 911,858,407,772,808, is 1.
Now, the common factors can be found like this.
911:911
858:2x 3x 11x 13
407:11x 37
772:2x 2x 193
808:2x 2x 2x 101
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 = 198439779210816/(1x88)
LCM = 198439779210816/88
LCM = 2254997491032
Thus, we can understand that the LCM of 911,858,407,772,808 is 2254997491032.
