Given numbers are 309,843,632,401,788
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 309,843,632,401,788 is 4335033684216.
Find LCM of 309,843,632,401,788 with Prime Factorization
| 2 | 309, 843, 632, 401, 788 |
| 2 | 309, 843, 316, 401, 394 |
| 3 | 309, 843, 158, 401, 197 |
| 103, 281, 158, 401, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 103 x 281 x 158 x 401 x 197 = 4335033684216
Therefore, the lowest common multiple of 309,843,632,401,788 is 4335033684216.
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.
309 x 843 x 632 x 401 x 788 = 52020404210592
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.
309 : 1, 3, 103, 309
843 : 1, 3, 281, 843
632 : 1, 2, 4, 8, 79, 158, 316, 632
401 : 1, 401
788 : 1, 2, 4, 197, 394, 788
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 309,843,632,401,788, is 1.
Now, the common factors can be found like this.
309:3x 103
843:3x 281
632:2x 2x 2x 79
401:401
788:2x 2x 197
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 = 52020404210592/(1x12)
LCM = 52020404210592/12
LCM = 4335033684216
Thus, we can understand that the LCM of 309,843,632,401,788 is 4335033684216.
