Given numbers are 677,408,789,764
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 677,408,789,764 is 13875158328.
Find LCM of 677,408,789,764 with Prime Factorization
2 | 677, 408, 789, 764 |
2 | 677, 204, 789, 382 |
3 | 677, 102, 789, 191 |
677, 34, 263, 191 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 677 x 34 x 263 x 191 = 13875158328
Therefore, the lowest common multiple of 677,408,789,764 is 13875158328.
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 408 x 789 x 764 = 166501899936
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
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
789 : 1, 3, 263, 789
764 : 1, 2, 4, 191, 382, 764
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 677,408,789,764, is 1.
Now, the common factors can be found like this.
677:677
408:2x 2x 2x 3x 17
789:3x 263
764:2x 2x 191
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 = 166501899936/(1x12)
LCM = 166501899936/12
LCM = 13875158328
Thus, we can understand that the LCM of 677,408,789,764 is 13875158328.
