The LCM of 398,208,623,676,546 is 1005701424.
Find LCM of 398,208,623,676,546 with Prime Factorization
| 2 | 398, 208, 623, 676, 546 |
| 2 | 199, 104, 623, 338, 273 |
| 7 | 199, 52, 623, 169, 273 |
| 13 | 199, 52, 89, 169, 39 |
| 199, 4, 89, 13, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 13 x 199 x 4 x 89 x 13 x 3 = 1005701424
Therefore, the lowest common multiple of 398,208,623,676,546 is 1005701424.
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.
398 x 208 x 623 x 676 x 546 = 19035916553472
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.
398 : 1, 2, 199, 398
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
623 : 1, 7, 89, 623
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,208,623,676,546, is 1.
Now, the common factors can be found like this.
398:2x 199
208:2x 2x 2x 2x 13
623:7x 89
676:2x 2x 13x 13
546:2x 3x 7x 13
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 2x 7x 13x 13 = 18928
Therefore, the value for common factors is 18928.
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 = 19035916553472/(1x18928)
LCM = 19035916553472/18928
LCM = 1005701424
Thus, we can understand that the LCM of 398,208,623,676,546 is 1005701424.
