Given numbers are 195,977,447,486,689
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 195,977,447,486,689 is 243728506710.
Find LCM of 195,977,447,486,689 with Prime Factorization
| 3 | 195, 977, 447, 486, 689 |
| 13 | 65, 977, 149, 162, 689 |
| 5, 977, 149, 162, 53 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 5 x 977 x 149 x 162 x 53 = 243728506710
Therefore, the lowest common multiple of 195,977,447,486,689 is 243728506710.
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.
195 x 977 x 447 x 486 x 689 = 28516235285070
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.
195 : 1, 3, 5, 13, 15, 39, 65, 195
977 : 1, 977
447 : 1, 3, 149, 447
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 195,977,447,486,689, is 1.
Now, the common factors can be found like this.
195:3x 5x 13
977:977
447:3x 149
486:2x 3x 3x 3x 3x 3
689:13x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 13 = 117
Therefore, the value for common factors is 117.
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 = 28516235285070/(1x117)
LCM = 28516235285070/117
LCM = 243728506710
Thus, we can understand that the LCM of 195,977,447,486,689 is 243728506710.
