Given numbers are 420,726,206,227,857
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 420,726,206,227,857 is 1018306613940.
Find LCM of 420,726,206,227,857 with Prime Factorization
| 2 | 420, 726, 206, 227, 857 |
| 3 | 210, 363, 103, 227, 857 |
| 70, 121, 103, 227, 857 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 70 x 121 x 103 x 227 x 857 = 1018306613940
Therefore, the lowest common multiple of 420,726,206,227,857 is 1018306613940.
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.
420 x 726 x 206 x 227 x 857 = 12219679367280
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.
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
206 : 1, 2, 103, 206
227 : 1, 227
857 : 1, 857
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,726,206,227,857, is 1.
Now, the common factors can be found like this.
420:2x 2x 3x 5x 7
726:2x 3x 11x 11
206:2x 103
227:227
857:857
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 3 = 12
Therefore, the value for common factors is 12.
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 = 12219679367280/(1x12)
LCM = 12219679367280/12
LCM = 1018306613940
Thus, we can understand that the LCM of 420,726,206,227,857 is 1018306613940.
