Find LCM of 486,989,112,378,689 with Prime Factorization
| 2 | 486, 989, 112, 378, 689 |
| 3 | 243, 989, 56, 189, 689 |
| 3 | 81, 989, 56, 63, 689 |
| 3 | 27, 989, 56, 21, 689 |
| 7 | 9, 989, 56, 7, 689 |
| 9, 989, 8, 1, 689 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 7 x 9 x 989 x 8 x 1 x 689 = 18545553936
Therefore, the lowest common multiple of 486,989,112,378,689 is 18545553936.
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.
486 x 989 x 112 x 378 x 689 = 14020438775616
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.
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
989 : 1, 23, 43, 989
112 : 1, 2, 4, 7, 8, 14, 16, 28, 56, 112
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 486,989,112,378,689, is 1.
Now, the common factors can be found like this.
486:2x 3x 3x 3x 3x 3
989:23x 43
112:2x 2x 2x 2x 7
378:2x 3x 3x 3x 7
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.
2x 2x 3x 3x 3x 7 = 756
Therefore, the value for common factors is 756.
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 = 14020438775616/(1x756)
LCM = 14020438775616/756
LCM = 18545553936
Thus, we can understand that the LCM of 486,989,112,378,689 is 18545553936.
