Given numbers are 792,662,686,422
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 792,662,686,422 is 18972726696.
Find LCM of 792,662,686,422 with Prime Factorization
| 2 | 792, 662, 686, 422 |
| 396, 331, 343, 211 |
Multiply the prime numbers at the bottom and the left side.
2 x 396 x 331 x 343 x 211 = 18972726696
Therefore, the lowest common multiple of 792,662,686,422 is 18972726696.
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.
792 x 662 x 686 x 422 = 151781813568
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.
792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792
662 : 1, 2, 331, 662
686 : 1, 2, 7, 14, 49, 98, 343, 686
422 : 1, 2, 211, 422
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 792,662,686,422, is 2.
Now, the common factors can be found like this.
792:2x 2x 2x 3x 3x 11
662:2x 331
686:2x 7x 7x 7
422:2x 211
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 151781813568/(2x4)
LCM = 151781813568/8
LCM = 18972726696
Thus, we can understand that the LCM of 792,662,686,422 is 18972726696.
