Given numbers are 788,936,833,394
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 788,936,833,394 is 153598536.
Find LCM of 788,936,833,394 with Prime Factorization
| 2 | 788, 936, 833, 394 |
| 2 | 394, 468, 833, 197 |
| 197 | 197, 234, 833, 197 |
| 1, 234, 833, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 197 x 1 x 234 x 833 x 1 = 153598536
Therefore, the lowest common multiple of 788,936,833,394 is 153598536.
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.
788 x 936 x 833 x 394 = 242071292736
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.
788 : 1, 2, 4, 197, 394, 788
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
833 : 1, 7, 17, 49, 119, 833
394 : 1, 2, 197, 394
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 788,936,833,394, is 1.
Now, the common factors can be found like this.
788:2x 2x 197
936:2x 2x 2x 3x 3x 13
833:7x 7x 17
394:2x 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 2x 197 = 1576
Therefore, the value for common factors is 1576.
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 = 242071292736/(1x1576)
LCM = 242071292736/1576
LCM = 153598536
Thus, we can understand that the LCM of 788,936,833,394 is 153598536.
