Given numbers are 546,390,391,771,844
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 546,390,391,771,844 is 115767053220.
Find LCM of 546,390,391,771,844 with Prime Factorization
| 2 | 546, 390, 391, 771, 844 |
| 3 | 273, 195, 391, 771, 422 |
| 13 | 91, 65, 391, 257, 422 |
| 7, 5, 391, 257, 422 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 7 x 5 x 391 x 257 x 422 = 115767053220
Therefore, the lowest common multiple of 546,390,391,771,844 is 115767053220.
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 390 x 391 x 771 x 844 = 54178980906960
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
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
391 : 1, 17, 23, 391
771 : 1, 3, 257, 771
844 : 1, 2, 4, 211, 422, 844
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 546,390,391,771,844, is 1.
Now, the common factors can be found like this.
546:2x 3x 7x 13
390:2x 3x 5x 13
391:17x 23
771:3x 257
844:2x 2x 211
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 3x 3x 13 = 468
Therefore, the value for common factors is 468.
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 = 54178980906960/(1x468)
LCM = 54178980906960/468
LCM = 115767053220
Thus, we can understand that the LCM of 546,390,391,771,844 is 115767053220.
