Find LCM of 269,957,209,546,646 with Prime Factorization
| 2 | 269, 957, 209, 546, 646 |
| 3 | 269, 957, 209, 273, 323 |
| 11 | 269, 319, 209, 91, 323 |
| 19 | 269, 29, 19, 91, 323 |
| 269, 29, 1, 91, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 19 x 269 x 29 x 1 x 91 x 17 = 15133456338
Therefore, the lowest common multiple of 269,957,209,546,646 is 15133456338.
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.
269 x 957 x 209 x 546 x 646 = 18977354247852
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.
269 : 1, 269
957 : 1, 3, 11, 29, 33, 87, 319, 957
209 : 1, 11, 19, 209
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 269,957,209,546,646, is 1.
Now, the common factors can be found like this.
269:269
957:3x 11x 29
209:11x 19
546:2x 3x 7x 13
646:2x 17x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 11x 19 = 1254
Therefore, the value for common factors is 1254.
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 = 18977354247852/(1x1254)
LCM = 18977354247852/1254
LCM = 15133456338
Thus, we can understand that the LCM of 269,957,209,546,646 is 15133456338.
