Given numbers are 323,546,309,540,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 323,546,309,540,781 is 1276808993460.
Find LCM of 323,546,309,540,781 with Prime Factorization
| 2 | 323, 546, 309, 540, 781 |
| 3 | 323, 273, 309, 270, 781 |
| 323, 91, 103, 90, 781 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 323 x 91 x 103 x 90 x 781 = 1276808993460
Therefore, the lowest common multiple of 323,546,309,540,781 is 1276808993460.
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.
323 x 546 x 309 x 540 x 781 = 22982561882280
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.
323 : 1, 17, 19, 323
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
309 : 1, 3, 103, 309
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 323,546,309,540,781, is 1.
Now, the common factors can be found like this.
323:17x 19
546:2x 3x 7x 13
309:3x 103
540:2x 2x 3x 3x 3x 5
781:11x 71
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 3 = 18
Therefore, the value for common factors is 18.
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 = 22982561882280/(1x18)
LCM = 22982561882280/18
LCM = 1276808993460
Thus, we can understand that the LCM of 323,546,309,540,781 is 1276808993460.
