Given numbers are 854,161,308,998,408
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 854,161,308,998,408 is 21994247352.
Find LCM of 854,161,308,998,408 with Prime Factorization
| 2 | 854, 161, 308, 998, 408 |
| 2 | 427, 161, 154, 499, 204 |
| 7 | 427, 161, 77, 499, 102 |
| 61, 23, 11, 499, 102 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 61 x 23 x 11 x 499 x 102 = 21994247352
Therefore, the lowest common multiple of 854,161,308,998,408 is 21994247352.
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.
854 x 161 x 308 x 998 x 408 = 17243489923968
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.
854 : 1, 2, 7, 14, 61, 122, 427, 854
161 : 1, 7, 23, 161
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
998 : 1, 2, 499, 998
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 854,161,308,998,408, is 1.
Now, the common factors can be found like this.
854:2x 7x 61
161:7x 23
308:2x 2x 7x 11
998:2x 499
408:2x 2x 2x 3x 17
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 2x 2x 7x 7 = 784
Therefore, the value for common factors is 784.
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 = 17243489923968/(1x784)
LCM = 17243489923968/784
LCM = 21994247352
Thus, we can understand that the LCM of 854,161,308,998,408 is 21994247352.
