The LCM of 397,674,171,337,678 is 5170409694.
Find LCM of 397,674,171,337,678 with Prime Factorization
| 2 | 397, 674, 171, 337, 678 |
| 3 | 397, 337, 171, 337, 339 |
| 337 | 397, 337, 57, 337, 113 |
| 397, 1, 57, 1, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 337 x 397 x 1 x 57 x 1 x 113 = 5170409694
Therefore, the lowest common multiple of 397,674,171,337,678 is 5170409694.
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.
397 x 674 x 171 x 337 x 678 = 10454568401268
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.
397 : 1, 397
674 : 1, 2, 337, 674
171 : 1, 3, 9, 19, 57, 171
337 : 1, 337
678 : 1, 2, 3, 6, 113, 226, 339, 678
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,674,171,337,678, is 1.
Now, the common factors can be found like this.
397:397
674:2x 337
171:3x 3x 19
337:337
678:2x 3x 113
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 337 = 2022
Therefore, the value for common factors is 2022.
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 = 10454568401268/(1x2022)
LCM = 10454568401268/2022
LCM = 5170409694
Thus, we can understand that the LCM of 397,674,171,337,678 is 5170409694.
