Given numbers are 211,891,869,431
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 211,891,869,431 is 6401246049.
Find LCM of 211,891,869,431 with Prime Factorization
| 11 | 211, 891, 869, 431 |
| 211, 81, 79, 431 |
Multiply the prime numbers at the bottom and the left side.
11 x 211 x 81 x 79 x 431 = 6401246049
Therefore, the lowest common multiple of 211,891,869,431 is 6401246049.
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 891 x 869 x 431 = 70413706539
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
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
869 : 1, 11, 79, 869
431 : 1, 431
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 211,891,869,431, is 1.
Now, the common factors can be found like this.
211:211
891:3x 3x 3x 3x 11
869:11x 79
431:431
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 70413706539/(1x11)
LCM = 70413706539/11
LCM = 6401246049
Thus, we can understand that the LCM of 211,891,869,431 is 6401246049.
