Given numbers are 791,690,818,857
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 791,690,818,857 is 191306490270.
Find LCM of 791,690,818,857 with Prime Factorization
2 | 791, 690, 818, 857 |
791, 345, 409, 857 |
Multiply the prime numbers at the bottom and the left side.
2 x 791 x 345 x 409 x 857 = 191306490270
Therefore, the lowest common multiple of 791,690,818,857 is 191306490270.
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 690 x 818 x 857 = 382612980540
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
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
818 : 1, 2, 409, 818
857 : 1, 857
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,690,818,857, is 1.
Now, the common factors can be found like this.
791:7x 113
690:2x 3x 5x 23
818:2x 409
857:857
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 382612980540/(1x2)
LCM = 382612980540/2
LCM = 191306490270
Thus, we can understand that the LCM of 791,690,818,857 is 191306490270.
