Given numbers are 648,389,663,673,447
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 648,389,663,673,447 is 5586222291624.
Find LCM of 648,389,663,673,447 with Prime Factorization
| 3 | 648, 389, 663, 673, 447 |
| 216, 389, 221, 673, 149 |
Multiply the prime numbers at the bottom and the left side.
3 x 216 x 389 x 221 x 673 x 149 = 5586222291624
Therefore, the lowest common multiple of 648,389,663,673,447 is 5586222291624.
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.
648 x 389 x 663 x 673 x 447 = 50276000624616
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.
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
389 : 1, 389
663 : 1, 3, 13, 17, 39, 51, 221, 663
673 : 1, 673
447 : 1, 3, 149, 447
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 648,389,663,673,447, is 1.
Now, the common factors can be found like this.
648:2x 2x 2x 3x 3x 3x 3
389:389
663:3x 13x 17
673:673
447:3x 149
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 50276000624616/(1x9)
LCM = 50276000624616/9
LCM = 5586222291624
Thus, we can understand that the LCM of 648,389,663,673,447 is 5586222291624.
