Given numbers are 677,651,821,468,268
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 677,651,821,468,268 is 3781918933884.
Find LCM of 677,651,821,468,268 with Prime Factorization
| 2 | 677, 651, 821, 468, 268 |
| 2 | 677, 651, 821, 234, 134 |
| 3 | 677, 651, 821, 117, 67 |
| 677, 217, 821, 39, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 677 x 217 x 821 x 39 x 67 = 3781918933884
Therefore, the lowest common multiple of 677,651,821,468,268 is 3781918933884.
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.
677 x 651 x 821 x 468 x 268 = 45383027206608
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.
677 : 1, 677
651 : 1, 3, 7, 21, 31, 93, 217, 651
821 : 1, 821
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
268 : 1, 2, 4, 67, 134, 268
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 677,651,821,468,268, is 1.
Now, the common factors can be found like this.
677:677
651:3x 7x 31
821:821
468:2x 2x 3x 3x 13
268:2x 2x 67
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 = 45383027206608/(1x12)
LCM = 45383027206608/12
LCM = 3781918933884
Thus, we can understand that the LCM of 677,651,821,468,268 is 3781918933884.
