Given numbers are 826,637,939,441
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 826,637,939,441 is 211742622.
Find LCM of 826,637,939,441 with Prime Factorization
| 3 | 826, 637, 939, 441 |
| 7 | 826, 637, 313, 147 |
| 7 | 118, 91, 313, 21 |
| 118, 13, 313, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 7 x 118 x 13 x 313 x 3 = 211742622
Therefore, the lowest common multiple of 826,637,939,441 is 211742622.
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.
826 x 637 x 939 x 441 = 217883158038
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.
826 : 1, 2, 7, 14, 59, 118, 413, 826
637 : 1, 7, 13, 49, 91, 637
939 : 1, 3, 313, 939
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 826,637,939,441, is 1.
Now, the common factors can be found like this.
826:2x 7x 59
637:7x 7x 13
939:3x 313
441:3x 3x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 7x 7 = 1029
Therefore, the value for common factors is 1029.
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 = 217883158038/(1x1029)
LCM = 217883158038/1029
LCM = 211742622
Thus, we can understand that the LCM of 826,637,939,441 is 211742622.
