Given numbers are 993,978,609,252
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 993,978,609,252 is 394288524.
Find LCM of 993,978,609,252 with Prime Factorization
| 2 | 993, 978, 609, 252 |
| 3 | 993, 489, 609, 126 |
| 7 | 331, 163, 203, 42 |
| 331, 163, 29, 6 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 331 x 163 x 29 x 6 = 394288524
Therefore, the lowest common multiple of 993,978,609,252 is 394288524.
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 978 x 609 x 252 = 149041062072
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
978 : 1, 2, 3, 6, 163, 326, 489, 978
609 : 1, 3, 7, 21, 29, 87, 203, 609
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 993,978,609,252, is 3.
Now, the common factors can be found like this.
993:3x 331
978:2x 3x 163
609:3x 7x 29
252:2x 2x 3x 3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 7 = 126
Therefore, the value for common factors is 126.
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 = 149041062072/(3x126)
LCM = 149041062072/378
LCM = 394288524
Thus, we can understand that the LCM of 993,978,609,252 is 394288524.
