Given numbers are 691,793,794,218,976
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 691,793,794,218,976 is 379392046384.
Find LCM of 691,793,794,218,976 with Prime Factorization
| 2 | 691, 793, 794, 218, 976 |
| 61 | 691, 793, 397, 109, 488 |
| 691, 13, 397, 109, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 61 x 691 x 13 x 397 x 109 x 8 = 379392046384
Therefore, the lowest common multiple of 691,793,794,218,976 is 379392046384.
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.
691 x 793 x 794 x 218 x 976 = 92571659317696
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.
691 : 1, 691
793 : 1, 13, 61, 793
794 : 1, 2, 397, 794
218 : 1, 2, 109, 218
976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 691,793,794,218,976, is 1.
Now, the common factors can be found like this.
691:691
793:13x 61
794:2x 397
218:2x 109
976:2x 2x 2x 2x 61
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 61 = 244
Therefore, the value for common factors is 244.
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 = 92571659317696/(1x244)
LCM = 92571659317696/244
LCM = 379392046384
Thus, we can understand that the LCM of 691,793,794,218,976 is 379392046384.
