Given numbers are 647,671,867,213
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 647,671,867,213 is 26724171309.
Find LCM of 647,671,867,213 with Prime Factorization
| 3 | 647, 671, 867, 213 |
| 647, 671, 289, 71 |
Multiply the prime numbers at the bottom and the left side.
3 x 647 x 671 x 289 x 71 = 26724171309
Therefore, the lowest common multiple of 647,671,867,213 is 26724171309.
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.
647 x 671 x 867 x 213 = 80172513927
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.
647 : 1, 647
671 : 1, 11, 61, 671
867 : 1, 3, 17, 51, 289, 867
213 : 1, 3, 71, 213
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,671,867,213, is 1.
Now, the common factors can be found like this.
647:647
671:11x 61
867:3x 17x 17
213:3x 71
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 = 80172513927/(1x3)
LCM = 80172513927/3
LCM = 26724171309
Thus, we can understand that the LCM of 647,671,867,213 is 26724171309.
