Given numbers are 774,885,238,731,802
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 774,885,238,731,802 is 10895679270.
Find LCM of 774,885,238,731,802 with Prime Factorization
| 2 | 774, 885, 238, 731, 802 |
| 3 | 387, 885, 119, 731, 401 |
| 17 | 129, 295, 119, 731, 401 |
| 43 | 129, 295, 7, 43, 401 |
| 3, 295, 7, 1, 401 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 43 x 3 x 295 x 7 x 1 x 401 = 10895679270
Therefore, the lowest common multiple of 774,885,238,731,802 is 10895679270.
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.
774 x 885 x 238 x 731 x 802 = 95576898556440
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.
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
885 : 1, 3, 5, 15, 59, 177, 295, 885
238 : 1, 2, 7, 14, 17, 34, 119, 238
731 : 1, 17, 43, 731
802 : 1, 2, 401, 802
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 774,885,238,731,802, is 1.
Now, the common factors can be found like this.
774:2x 3x 3x 43
885:3x 5x 59
238:2x 7x 17
731:17x 43
802:2x 401
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 17x 43 = 8772
Therefore, the value for common factors is 8772.
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 = 95576898556440/(1x8772)
LCM = 95576898556440/8772
LCM = 10895679270
Thus, we can understand that the LCM of 774,885,238,731,802 is 10895679270.
