The LCM of 252,309,136,578 is 15002568.
Find LCM of 252,309,136,578 with Prime Factorization
| 2 | 252, 309, 136, 578 |
| 2 | 126, 309, 68, 289 |
| 3 | 63, 309, 34, 289 |
| 17 | 21, 103, 34, 289 |
| 21, 103, 2, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 17 x 21 x 103 x 2 x 17 = 15002568
Therefore, the lowest common multiple of 252,309,136,578 is 15002568.
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.
252 x 309 x 136 x 578 = 6121047744
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.
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
309 : 1, 3, 103, 309
136 : 1, 2, 4, 8, 17, 34, 68, 136
578 : 1, 2, 17, 34, 289, 578
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 252,309,136,578, is 1.
Now, the common factors can be found like this.
252:2x 2x 3x 3x 7
309:3x 103
136:2x 2x 2x 17
578:2x 17x 17
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 3x 17 = 408
Therefore, the value for common factors is 408.
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 = 6121047744/(1x408)
LCM = 6121047744/408
LCM = 15002568
Thus, we can understand that the LCM of 252,309,136,578 is 15002568.
