The LCM of 460,690,494,904,765 is 3928752360.
Find LCM of 460,690,494,904,765 with Prime Factorization
| 2 | 460, 690, 494, 904, 765 |
| 2 | 230, 345, 247, 452, 765 |
| 3 | 115, 345, 247, 226, 765 |
| 5 | 115, 115, 247, 226, 255 |
| 23 | 23, 23, 247, 226, 51 |
| 1, 1, 247, 226, 51 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 23 x 1 x 1 x 247 x 226 x 51 = 3928752360
Therefore, the lowest common multiple of 460,690,494,904,765 is 3928752360.
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.
460 x 690 x 494 x 904 x 765 = 108433565136000
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.
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
494 : 1, 2, 13, 19, 26, 38, 247, 494
904 : 1, 2, 4, 8, 113, 226, 452, 904
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 460,690,494,904,765, is 1.
Now, the common factors can be found like this.
460:2x 2x 5x 23
690:2x 3x 5x 23
494:2x 13x 19
904:2x 2x 2x 113
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 2x 2x 2x 3x 5x 5x 23 = 27600
Therefore, the value for common factors is 27600.
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 = 108433565136000/(1x27600)
LCM = 108433565136000/27600
LCM = 3928752360
Thus, we can understand that the LCM of 460,690,494,904,765 is 3928752360.
