The LCM of 405,241,778,704,765 is 454405152960.
Find LCM of 405,241,778,704,765 with Prime Factorization
| 2 | 405, 241, 778, 704, 765 |
| 3 | 405, 241, 389, 352, 765 |
| 3 | 135, 241, 389, 352, 255 |
| 5 | 45, 241, 389, 352, 85 |
| 9, 241, 389, 352, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 9 x 241 x 389 x 352 x 17 = 454405152960
Therefore, the lowest common multiple of 405,241,778,704,765 is 454405152960.
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.
405 x 241 x 778 x 704 x 765 = 40896463766400
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.
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
241 : 1, 241
778 : 1, 2, 389, 778
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 405,241,778,704,765, is 1.
Now, the common factors can be found like this.
405:3x 3x 3x 3x 5
241:241
778:2x 389
704:2x 2x 2x 2x 2x 2x 11
765:3x 3x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5 = 90
Therefore, the value for common factors is 90.
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 = 40896463766400/(1x90)
LCM = 40896463766400/90
LCM = 454405152960
Thus, we can understand that the LCM of 405,241,778,704,765 is 454405152960.
