Given numbers are 538,904,678,215,247
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 538,904,678,215,247 is 38741584440.
Find LCM of 538,904,678,215,247 with Prime Factorization
| 2 | 538, 904, 678, 215, 247 |
| 113 | 269, 452, 339, 215, 247 |
| 269, 4, 3, 215, 247 |
Multiply the prime numbers at the bottom and the left side.
2 x 113 x 269 x 4 x 3 x 215 x 247 = 38741584440
Therefore, the lowest common multiple of 538,904,678,215,247 is 38741584440.
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.
538 x 904 x 678 x 215 x 247 = 17511196166880
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.
538 : 1, 2, 269, 538
904 : 1, 2, 4, 8, 113, 226, 452, 904
678 : 1, 2, 3, 6, 113, 226, 339, 678
215 : 1, 5, 43, 215
247 : 1, 13, 19, 247
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 538,904,678,215,247, is 1.
Now, the common factors can be found like this.
538:2x 269
904:2x 2x 2x 113
678:2x 3x 113
215:5x 43
247:13x 19
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 113 = 452
Therefore, the value for common factors is 452.
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 = 17511196166880/(1x452)
LCM = 17511196166880/452
LCM = 38741584440
Thus, we can understand that the LCM of 538,904,678,215,247 is 38741584440.
