The LCM of 546,491,741,399 is 5093634.
Find LCM of 546,491,741,399 with Prime Factorization
| 3 | 546, 491, 741, 399 |
| 7 | 182, 491, 247, 133 |
| 13 | 26, 491, 247, 19 |
| 19 | 2, 491, 19, 19 |
| 2, 491, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 13 x 19 x 2 x 491 x 1 x 1 = 5093634
Therefore, the lowest common multiple of 546,491,741,399 is 5093634.
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 491 x 741 x 399 = 79262038674
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
491 : 1, 491
741 : 1, 3, 13, 19, 39, 57, 247, 741
399 : 1, 3, 7, 19, 21, 57, 133, 399
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 546,491,741,399, is 1.
Now, the common factors can be found like this.
546:2x 3x 7x 13
491:491
741:3x 13x 19
399:3x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 7x 13x 19 = 15561
Therefore, the value for common factors is 15561.
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 = 79262038674/(1x15561)
LCM = 79262038674/15561
LCM = 5093634
Thus, we can understand that the LCM of 546,491,741,399 is 5093634.
