Find LCM of 643,735,815,572,832 with Prime Factorization
| 2 | 643, 735, 815, 572, 832 |
| 2 | 643, 735, 815, 286, 416 |
| 5 | 643, 735, 815, 143, 208 |
| 13 | 643, 147, 163, 143, 208 |
| 643, 147, 163, 11, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 643 x 147 x 163 x 11 x 16 = 705020796480
Therefore, the lowest common multiple of 643,735,815,572,832 is 705020796480.
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.
643 x 735 x 815 x 572 x 832 = 183305407084800
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.
643 : 1, 643
735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735
815 : 1, 5, 163, 815
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
832 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 64, 104, 208, 416, 832
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,735,815,572,832, is 1.
Now, the common factors can be found like this.
643:643
735:3x 5x 7x 7
815:5x 163
572:2x 2x 11x 13
832:2x 2x 2x 2x 2x 2x 13
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 5x 13 = 260
Therefore, the value for common factors is 260.
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 = 183305407084800/(1x260)
LCM = 183305407084800/260
LCM = 705020796480
Thus, we can understand that the LCM of 643,735,815,572,832 is 705020796480.
