Given numbers are 671,671,993,216
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 671,671,993,216 is 47973816.
Find LCM of 671,671,993,216 with Prime Factorization
| 3 | 671, 671, 993, 216 |
| 11 | 671, 671, 331, 72 |
| 61 | 61, 61, 331, 72 |
| 1, 1, 331, 72 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 61 x 1 x 1 x 331 x 72 = 47973816
Therefore, the lowest common multiple of 671,671,993,216 is 47973816.
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.
671 x 671 x 993 x 216 = 96571291608
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.
671 : 1, 11, 61, 671
671 : 1, 11, 61, 671
993 : 1, 3, 331, 993
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,671,993,216, is 1.
Now, the common factors can be found like this.
671:11x 61
671:11x 61
993:3x 331
216:2x 2x 2x 3x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 61 = 2013
Therefore, the value for common factors is 2013.
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 = 96571291608/(1x2013)
LCM = 96571291608/2013
LCM = 47973816
Thus, we can understand that the LCM of 671,671,993,216 is 47973816.
