Given numbers are 657,903,808,798,178
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 657,903,808,798,178 is 270200926296.
Find LCM of 657,903,808,798,178 with Prime Factorization
| 2 | 657, 903, 808, 798, 178 |
| 3 | 657, 903, 404, 399, 89 |
| 7 | 219, 301, 404, 133, 89 |
| 219, 43, 404, 19, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 219 x 43 x 404 x 19 x 89 = 270200926296
Therefore, the lowest common multiple of 657,903,808,798,178 is 270200926296.
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.
657 x 903 x 808 x 798 x 178 = 68090633426592
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.
657 : 1, 3, 9, 73, 219, 657
903 : 1, 3, 7, 21, 43, 129, 301, 903
808 : 1, 2, 4, 8, 101, 202, 404, 808
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
178 : 1, 2, 89, 178
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 657,903,808,798,178, is 1.
Now, the common factors can be found like this.
657:3x 3x 73
903:3x 7x 43
808:2x 2x 2x 101
798:2x 3x 7x 19
178:2x 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 2x 3x 3x 7 = 252
Therefore, the value for common factors is 252.
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 = 68090633426592/(1x252)
LCM = 68090633426592/252
LCM = 270200926296
Thus, we can understand that the LCM of 657,903,808,798,178 is 270200926296.
