Find LCM of 815,635,794,918,762 with Prime Factorization
| 2 | 815, 635, 794, 918, 762 |
| 3 | 815, 635, 397, 459, 381 |
| 5 | 815, 635, 397, 153, 127 |
| 127 | 163, 127, 397, 153, 127 |
| 163, 1, 397, 153, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 127 x 163 x 1 x 397 x 153 x 1 = 37721983230
Therefore, the lowest common multiple of 815,635,794,918,762 is 37721983230.
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.
815 x 635 x 794 x 918 x 762 = 287441512212600
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.
815 : 1, 5, 163, 815
635 : 1, 5, 127, 635
794 : 1, 2, 397, 794
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
762 : 1, 2, 3, 6, 127, 254, 381, 762
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 815,635,794,918,762, is 1.
Now, the common factors can be found like this.
815:5x 163
635:5x 127
794:2x 397
918:2x 3x 3x 3x 17
762:2x 3x 127
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 5x 127 = 7620
Therefore, the value for common factors is 7620.
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 = 287441512212600/(1x7620)
LCM = 287441512212600/7620
LCM = 37721983230
Thus, we can understand that the LCM of 815,635,794,918,762 is 37721983230.
