Given numbers are 487,378,908,623
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 487,378,908,623 is 7438178916.
Find LCM of 487,378,908,623 with Prime Factorization
| 2 | 487, 378, 908, 623 |
| 7 | 487, 189, 454, 623 |
| 487, 27, 454, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 487 x 27 x 454 x 89 = 7438178916
Therefore, the lowest common multiple of 487,378,908,623 is 7438178916.
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.
487 x 378 x 908 x 623 = 104134504824
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.
487 : 1, 487
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
908 : 1, 2, 4, 227, 454, 908
623 : 1, 7, 89, 623
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 487,378,908,623, is 1.
Now, the common factors can be found like this.
487:487
378:2x 3x 3x 3x 7
908:2x 2x 227
623:7x 89
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7 = 14
Therefore, the value for common factors is 14.
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 = 104134504824/(1x14)
LCM = 104134504824/14
LCM = 7438178916
Thus, we can understand that the LCM of 487,378,908,623 is 7438178916.
