Given numbers are 557,378,781,568,227
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 557,378,781,568,227 is 149308274808.
Find LCM of 557,378,781,568,227 with Prime Factorization
| 2 | 557, 378, 781, 568, 227 |
| 71 | 557, 189, 781, 284, 227 |
| 557, 189, 11, 4, 227 |
Multiply the prime numbers at the bottom and the left side.
2 x 71 x 557 x 189 x 11 x 4 x 227 = 149308274808
Therefore, the lowest common multiple of 557,378,781,568,227 is 149308274808.
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.
557 x 378 x 781 x 568 x 227 = 21201775022736
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.
557 : 1, 557
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
781 : 1, 11, 71, 781
568 : 1, 2, 4, 8, 71, 142, 284, 568
227 : 1, 227
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 557,378,781,568,227, is 1.
Now, the common factors can be found like this.
557:557
378:2x 3x 3x 3x 7
781:11x 71
568:2x 2x 2x 71
227:227
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 71 = 142
Therefore, the value for common factors is 142.
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 = 21201775022736/(1x142)
LCM = 21201775022736/142
LCM = 149308274808
Thus, we can understand that the LCM of 557,378,781,568,227 is 149308274808.
