Given numbers are 993,336,982,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 993,336,982,638 is 17419650864.
Find LCM of 993,336,982,638 with Prime Factorization
| 2 | 993, 336, 982, 638 |
| 3 | 993, 168, 491, 319 |
| 331, 56, 491, 319 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 331 x 56 x 491 x 319 = 17419650864
Therefore, the lowest common multiple of 993,336,982,638 is 17419650864.
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.
993 x 336 x 982 x 638 = 209035810368
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.
993 : 1, 3, 331, 993
336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336
982 : 1, 2, 491, 982
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 993,336,982,638, is 1.
Now, the common factors can be found like this.
993:3x 331
336:2x 2x 2x 2x 3x 7
982:2x 491
638:2x 11x 29
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 3 = 12
Therefore, the value for common factors is 12.
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 = 209035810368/(1x12)
LCM = 209035810368/12
LCM = 17419650864
Thus, we can understand that the LCM of 993,336,982,638 is 17419650864.
