The LCM of 546,916,687,427 is 15254148.
Find LCM of 546,916,687,427 with Prime Factorization
| 2 | 546, 916, 687, 427 |
| 3 | 273, 458, 687, 427 |
| 7 | 91, 458, 229, 427 |
| 229 | 13, 458, 229, 61 |
| 13, 2, 1, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 229 x 13 x 2 x 1 x 61 = 15254148
Therefore, the lowest common multiple of 546,916,687,427 is 15254148.
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.
546 x 916 x 687 x 427 = 146714395464
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.
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
916 : 1, 2, 4, 229, 458, 916
687 : 1, 3, 229, 687
427 : 1, 7, 61, 427
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 546,916,687,427, is 1.
Now, the common factors can be found like this.
546:2x 3x 7x 13
916:2x 2x 229
687:3x 229
427:7x 61
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 7x 229 = 9618
Therefore, the value for common factors is 9618.
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 = 146714395464/(1x9618)
LCM = 146714395464/9618
LCM = 15254148
Thus, we can understand that the LCM of 546,916,687,427 is 15254148.
