Given numbers are 993,649,893,489
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 993,649,893,489 is 93806516463.
Find LCM of 993,649,893,489 with Prime Factorization
| 3 | 993, 649, 893, 489 |
| 331, 649, 893, 163 |
Multiply the prime numbers at the bottom and the left side.
3 x 331 x 649 x 893 x 163 = 93806516463
Therefore, the lowest common multiple of 993,649,893,489 is 93806516463.
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 649 x 893 x 489 = 281419549389
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
649 : 1, 11, 59, 649
893 : 1, 19, 47, 893
489 : 1, 3, 163, 489
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 993,649,893,489, is 1.
Now, the common factors can be found like this.
993:3x 331
649:11x 59
893:19x 47
489:3x 163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 281419549389/(1x3)
LCM = 281419549389/3
LCM = 93806516463
Thus, we can understand that the LCM of 993,649,893,489 is 93806516463.
