The LCM of 994,561,486,432 is 361346832.
Find LCM of 994,561,486,432 with Prime Factorization
| 2 | 994, 561, 486, 432 |
| 3 | 497, 561, 243, 216 |
| 3 | 497, 187, 81, 72 |
| 3 | 497, 187, 27, 24 |
| 497, 187, 9, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 497 x 187 x 9 x 8 = 361346832
Therefore, the lowest common multiple of 994,561,486,432 is 361346832.
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.
994 x 561 x 486 x 432 = 117076373568
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.
994 : 1, 2, 7, 14, 71, 142, 497, 994
561 : 1, 3, 11, 17, 33, 51, 187, 561
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 994,561,486,432, is 1.
Now, the common factors can be found like this.
994:2x 7x 71
561:3x 11x 17
486:2x 3x 3x 3x 3x 3
432:2x 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.
2x 2x 3x 3x 3x 3 = 324
Therefore, the value for common factors is 324.
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 = 117076373568/(1x324)
LCM = 117076373568/324
LCM = 361346832
Thus, we can understand that the LCM of 994,561,486,432 is 361346832.
