Given numbers are 677,420,886,662,291
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 677,420,886,662,291 is 4044281840340.
Find LCM of 677,420,886,662,291 with Prime Factorization
| 2 | 677, 420, 886, 662, 291 |
| 3 | 677, 210, 443, 331, 291 |
| 677, 70, 443, 331, 97 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 677 x 70 x 443 x 331 x 97 = 4044281840340
Therefore, the lowest common multiple of 677,420,886,662,291 is 4044281840340.
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 420 x 886 x 662 x 291 = 48531382084080
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
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
886 : 1, 2, 443, 886
662 : 1, 2, 331, 662
291 : 1, 3, 97, 291
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 677,420,886,662,291, is 1.
Now, the common factors can be found like this.
677:677
420:2x 2x 3x 5x 7
886:2x 443
662:2x 331
291:3x 97
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 = 48531382084080/(1x12)
LCM = 48531382084080/12
LCM = 4044281840340
Thus, we can understand that the LCM of 677,420,886,662,291 is 4044281840340.
