Given numbers are 677,771,409,813
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 677,771,409,813 is 57854300313.
Find LCM of 677,771,409,813 with Prime Factorization
| 3 | 677, 771, 409, 813 |
| 677, 257, 409, 271 |
Multiply the prime numbers at the bottom and the left side.
3 x 677 x 257 x 409 x 271 = 57854300313
Therefore, the lowest common multiple of 677,771,409,813 is 57854300313.
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 771 x 409 x 813 = 173562900939
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
771 : 1, 3, 257, 771
409 : 1, 409
813 : 1, 3, 271, 813
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 677,771,409,813, is 1.
Now, the common factors can be found like this.
677:677
771:3x 257
409:409
813:3x 271
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 173562900939/(1x3)
LCM = 173562900939/3
LCM = 57854300313
Thus, we can understand that the LCM of 677,771,409,813 is 57854300313.
