Find LCM of 676,510,391,469,765 with Prime Factorization
| 2 | 676, 510, 391, 469, 765 |
| 3 | 338, 255, 391, 469, 765 |
| 5 | 338, 85, 391, 469, 255 |
| 17 | 338, 17, 391, 469, 51 |
| 338, 1, 23, 469, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 17 x 338 x 1 x 23 x 469 x 3 = 5578389180
Therefore, the lowest common multiple of 676,510,391,469,765 is 5578389180.
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.
676 x 510 x 391 x 469 x 765 = 48364634190600
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.
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
510 : 1, 2, 3, 5, 6, 10, 15, 17, 30, 34, 51, 85, 102, 170, 255, 510
391 : 1, 17, 23, 391
469 : 1, 7, 67, 469
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 676,510,391,469,765, is 1.
Now, the common factors can be found like this.
676:2x 2x 13x 13
510:2x 3x 5x 17
391:17x 23
469:7x 67
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 5x 17x 17 = 8670
Therefore, the value for common factors is 8670.
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 = 48364634190600/(1x8670)
LCM = 48364634190600/8670
LCM = 5578389180
Thus, we can understand that the LCM of 676,510,391,469,765 is 5578389180.
