Given numbers are 124,394,690,417,904
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 124,394,690,417,904 is 264746511240.
Find LCM of 124,394,690,417,904 with Prime Factorization
| 2 | 124, 394, 690, 417, 904 |
| 2 | 62, 197, 345, 417, 452 |
| 3 | 31, 197, 345, 417, 226 |
| 31, 197, 115, 139, 226 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 31 x 197 x 115 x 139 x 226 = 264746511240
Therefore, the lowest common multiple of 124,394,690,417,904 is 264746511240.
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.
124 x 394 x 690 x 417 x 904 = 12707832539520
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.
124 : 1, 2, 4, 31, 62, 124
394 : 1, 2, 197, 394
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
417 : 1, 3, 139, 417
904 : 1, 2, 4, 8, 113, 226, 452, 904
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 124,394,690,417,904, is 1.
Now, the common factors can be found like this.
124:2x 2x 31
394:2x 197
690:2x 3x 5x 23
417:3x 139
904:2x 2x 2x 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 2x 2x 2x 3 = 48
Therefore, the value for common factors is 48.
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 = 12707832539520/(1x48)
LCM = 12707832539520/48
LCM = 264746511240
Thus, we can understand that the LCM of 124,394,690,417,904 is 264746511240.
