Find LCM of 875,689,765,459 with Prime Factorization
| 3 | 875, 689, 765, 459 |
| 3 | 875, 689, 255, 153 |
| 5 | 875, 689, 85, 51 |
| 17 | 175, 689, 17, 51 |
| 175, 689, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 17 x 175 x 689 x 1 x 3 = 276719625
Therefore, the lowest common multiple of 875,689,765,459 is 276719625.
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.
875 x 689 x 765 x 459 = 211690513125
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.
875 : 1, 5, 7, 25, 35, 125, 175, 875
689 : 1, 13, 53, 689
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
459 : 1, 3, 9, 17, 27, 51, 153, 459
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 875,689,765,459, is 1.
Now, the common factors can be found like this.
875:5x 5x 5x 7
689:13x 53
765:3x 3x 5x 17
459:3x 3x 3x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 17 = 765
Therefore, the value for common factors is 765.
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 = 211690513125/(1x765)
LCM = 211690513125/765
LCM = 276719625
Thus, we can understand that the LCM of 875,689,765,459 is 276719625.
