Given numbers are 791,686,566,779
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 791,686,566,779 is 17089385726.
Find LCM of 791,686,566,779 with Prime Factorization
| 2 | 791, 686, 566, 779 |
| 7 | 791, 343, 283, 779 |
| 113, 49, 283, 779 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 113 x 49 x 283 x 779 = 17089385726
Therefore, the lowest common multiple of 791,686,566,779 is 17089385726.
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.
791 x 686 x 566 x 779 = 239251400164
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.
791 : 1, 7, 113, 791
686 : 1, 2, 7, 14, 49, 98, 343, 686
566 : 1, 2, 283, 566
779 : 1, 19, 41, 779
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,686,566,779, is 1.
Now, the common factors can be found like this.
791:7x 113
686:2x 7x 7x 7
566:2x 283
779:19x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7 = 14
Therefore, the value for common factors is 14.
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 = 239251400164/(1x14)
LCM = 239251400164/14
LCM = 17089385726
Thus, we can understand that the LCM of 791,686,566,779 is 17089385726.
