Given numbers are 635,783,813
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 635,783,813 is 134742555.
Find LCM of 635,783,813 with Prime Factorization
| 3 | 635, 783, 813 |
| 635, 261, 271 |
Multiply the prime numbers at the bottom and the left side.
3 x 635 x 261 x 271 = 134742555
Therefore, the lowest common multiple of 635,783,813 is 134742555.
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.
635 x 783 x 813 = 404227665
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.
635 : 1, 5, 127, 635
783 : 1, 3, 9, 27, 29, 87, 261, 783
813 : 1, 3, 271, 813
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 635,783,813, is 1.
Now, the common factors can be found like this.
635:5x 127
783:3x 3x 3x 29
813:3x 271
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 404227665/(1x3)
LCM = 404227665/3
LCM = 134742555
Thus, we can understand that the LCM of 635,783,813 is 134742555.
