Find LCM of 731,689,855,663,106 with Prime Factorization
| 3 | 731, 689, 855, 663, 106 |
| 13 | 731, 689, 285, 221, 106 |
| 17 | 731, 53, 285, 17, 106 |
| 53 | 43, 53, 285, 1, 106 |
| 43, 1, 285, 1, 2 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 17 x 53 x 43 x 1 x 285 x 1 x 2 = 861256890
Therefore, the lowest common multiple of 731,689,855,663,106 is 861256890.
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.
731 x 689 x 855 x 663 x 106 = 30263705857710
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.
731 : 1, 17, 43, 731
689 : 1, 13, 53, 689
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
663 : 1, 3, 13, 17, 39, 51, 221, 663
106 : 1, 2, 53, 106
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,689,855,663,106, is 1.
Now, the common factors can be found like this.
731:17x 43
689:13x 53
855:3x 3x 5x 19
663:3x 13x 17
106:2x 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 13x 17x 53 = 35139
Therefore, the value for common factors is 35139.
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 = 30263705857710/(1x35139)
LCM = 30263705857710/35139
LCM = 861256890
Thus, we can understand that the LCM of 731,689,855,663,106 is 861256890.
