Given numbers are 851,644,386,579
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 851,644,386,579 is 13796412.
Find LCM of 851,644,386,579 with Prime Factorization
| 2 | 851, 644, 386, 579 |
| 23 | 851, 322, 193, 579 |
| 193 | 37, 14, 193, 579 |
| 37, 14, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 23 x 193 x 37 x 14 x 1 x 3 = 13796412
Therefore, the lowest common multiple of 851,644,386,579 is 13796412.
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.
851 x 644 x 386 x 579 = 122484545736
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.
851 : 1, 23, 37, 851
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
386 : 1, 2, 193, 386
579 : 1, 3, 193, 579
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 851,644,386,579, is 1.
Now, the common factors can be found like this.
851:23x 37
644:2x 2x 7x 23
386:2x 193
579:3x 193
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 23x 193 = 8878
Therefore, the value for common factors is 8878.
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 = 122484545736/(1x8878)
LCM = 122484545736/8878
LCM = 13796412
Thus, we can understand that the LCM of 851,644,386,579 is 13796412.
