Given numbers are 385,491,845,507
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 385,491,845,507 is 95840745.
Find LCM of 385,491,845,507 with Prime Factorization
| 5 | 385, 491, 845, 507 |
| 13 | 77, 491, 169, 507 |
| 13 | 77, 491, 13, 39 |
| 77, 491, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
5 x 13 x 13 x 77 x 491 x 1 x 3 = 95840745
Therefore, the lowest common multiple of 385,491,845,507 is 95840745.
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.
385 x 491 x 845 x 507 = 80985429525
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.
385 : 1, 5, 7, 11, 35, 55, 77, 385
491 : 1, 491
845 : 1, 5, 13, 65, 169, 845
507 : 1, 3, 13, 39, 169, 507
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 385,491,845,507, is 1.
Now, the common factors can be found like this.
385:5x 7x 11
491:491
845:5x 13x 13
507:3x 13x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 13x 13 = 845
Therefore, the value for common factors is 845.
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 = 80985429525/(1x845)
LCM = 80985429525/845
LCM = 95840745
Thus, we can understand that the LCM of 385,491,845,507 is 95840745.
