Find LCM of 517,352,144,673,787 with Prime Factorization
| 2 | 517, 352, 144, 673, 787 |
| 2 | 517, 176, 72, 673, 787 |
| 2 | 517, 88, 36, 673, 787 |
| 2 | 517, 44, 18, 673, 787 |
| 11 | 517, 22, 9, 673, 787 |
| 47, 2, 9, 673, 787 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 11 x 47 x 2 x 9 x 673 x 787 = 78862915296
Therefore, the lowest common multiple of 517,352,144,673,787 is 78862915296.
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.
517 x 352 x 144 x 673 x 787 = 13879873092096
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.
517 : 1, 11, 47, 517
352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
673 : 1, 673
787 : 1, 787
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 517,352,144,673,787, is 1.
Now, the common factors can be found like this.
517:11x 47
352:2x 2x 2x 2x 2x 11
144:2x 2x 2x 2x 3x 3
673:673
787:787
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 11 = 176
Therefore, the value for common factors is 176.
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 = 13879873092096/(1x176)
LCM = 13879873092096/176
LCM = 78862915296
Thus, we can understand that the LCM of 517,352,144,673,787 is 78862915296.
