Given numbers are 417,260,663,243,678
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 417,260,663,243,678 is 16870260420.
Find LCM of 417,260,663,243,678 with Prime Factorization
| 2 | 417, 260, 663, 243, 678 |
| 3 | 417, 130, 663, 243, 339 |
| 13 | 139, 130, 221, 81, 113 |
| 139, 10, 17, 81, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 139 x 10 x 17 x 81 x 113 = 16870260420
Therefore, the lowest common multiple of 417,260,663,243,678 is 16870260420.
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.
417 x 260 x 663 x 243 x 678 = 11842922814840
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.
417 : 1, 3, 139, 417
260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
663 : 1, 3, 13, 17, 39, 51, 221, 663
243 : 1, 3, 9, 27, 81, 243
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 417,260,663,243,678, is 1.
Now, the common factors can be found like this.
417:3x 139
260:2x 2x 5x 13
663:3x 13x 17
243:3x 3x 3x 3x 3
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 3x 3x 13 = 702
Therefore, the value for common factors is 702.
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 = 11842922814840/(1x702)
LCM = 11842922814840/702
LCM = 16870260420
Thus, we can understand that the LCM of 417,260,663,243,678 is 16870260420.
