Given numbers are 765,654,815,647,235
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 765,654,815,647,235 is 826623355590.
Find LCM of 765,654,815,647,235 with Prime Factorization
| 3 | 765, 654, 815, 647, 235 |
| 5 | 255, 218, 815, 647, 235 |
| 51, 218, 163, 647, 47 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 51 x 218 x 163 x 647 x 47 = 826623355590
Therefore, the lowest common multiple of 765,654,815,647,235 is 826623355590.
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.
765 x 654 x 815 x 647 x 235 = 61996751669250
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.
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
654 : 1, 2, 3, 6, 109, 218, 327, 654
815 : 1, 5, 163, 815
647 : 1, 647
235 : 1, 5, 47, 235
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 765,654,815,647,235, is 1.
Now, the common factors can be found like this.
765:3x 3x 5x 17
654:2x 3x 109
815:5x 163
647:647
235:5x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5 = 75
Therefore, the value for common factors is 75.
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 = 61996751669250/(1x75)
LCM = 61996751669250/75
LCM = 826623355590
Thus, we can understand that the LCM of 765,654,815,647,235 is 826623355590.
