Find LCM of 279,496,736,323,647 with Prime Factorization
| 2 | 279, 496, 736, 323, 647 |
| 2 | 279, 248, 368, 323, 647 |
| 2 | 279, 124, 184, 323, 647 |
| 2 | 279, 62, 92, 323, 647 |
| 31 | 279, 31, 46, 323, 647 |
| 9, 1, 46, 323, 647 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 31 x 9 x 1 x 46 x 323 x 647 = 42912994464
Therefore, the lowest common multiple of 279,496,736,323,647 is 42912994464.
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.
279 x 496 x 736 x 323 x 647 = 21284845254144
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.
279 : 1, 3, 9, 31, 93, 279
496 : 1, 2, 4, 8, 16, 31, 62, 124, 248, 496
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
323 : 1, 17, 19, 323
647 : 1, 647
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 279,496,736,323,647, is 1.
Now, the common factors can be found like this.
279:3x 3x 31
496:2x 2x 2x 2x 31
736:2x 2x 2x 2x 2x 23
323:17x 19
647:647
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 31 = 496
Therefore, the value for common factors is 496.
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 = 21284845254144/(1x496)
LCM = 21284845254144/496
LCM = 42912994464
Thus, we can understand that the LCM of 279,496,736,323,647 is 42912994464.
