Given numbers are 521,507,858,195
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 521,507,858,195 is 29056170.
Find LCM of 521,507,858,195 with Prime Factorization
| 3 | 521, 507, 858, 195 |
| 13 | 521, 169, 286, 65 |
| 521, 13, 22, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 521 x 13 x 22 x 5 = 29056170
Therefore, the lowest common multiple of 521,507,858,195 is 29056170.
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.
521 x 507 x 858 x 195 = 44194434570
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.
521 : 1, 521
507 : 1, 3, 13, 39, 169, 507
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
195 : 1, 3, 5, 13, 15, 39, 65, 195
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,507,858,195, is 1.
Now, the common factors can be found like this.
521:521
507:3x 13x 13
858:2x 3x 11x 13
195:3x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 13x 13 = 1521
Therefore, the value for common factors is 1521.
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 = 44194434570/(1x1521)
LCM = 44194434570/1521
LCM = 29056170
Thus, we can understand that the LCM of 521,507,858,195 is 29056170.
