Find LCM of 765,675,398,629 with Prime Factorization
| 3 | 765, 675, 398, 629 |
| 3 | 255, 225, 398, 629 |
| 5 | 85, 75, 398, 629 |
| 17 | 17, 15, 398, 629 |
| 1, 15, 398, 37 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 17 x 1 x 15 x 398 x 37 = 168980850
Therefore, the lowest common multiple of 765,675,398,629 is 168980850.
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 675 x 398 x 629 = 129270350250
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
675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
398 : 1, 2, 199, 398
629 : 1, 17, 37, 629
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 765,675,398,629, is 1.
Now, the common factors can be found like this.
765:3x 3x 5x 17
675:3x 3x 3x 5x 5
398:2x 199
629:17x 37
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 = 129270350250/(1x765)
LCM = 129270350250/765
LCM = 168980850
Thus, we can understand that the LCM of 765,675,398,629 is 168980850.
