Given numbers are 791,715,605,925
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 791,715,605,925 is 1150924775.
Find LCM of 791,715,605,925 with Prime Factorization
| 5 | 791, 715, 605, 925 |
| 11 | 791, 143, 121, 185 |
| 791, 13, 11, 185 |
Multiply the prime numbers at the bottom and the left side.
5 x 11 x 791 x 13 x 11 x 185 = 1150924775
Therefore, the lowest common multiple of 791,715,605,925 is 1150924775.
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 715 x 605 x 925 = 316504313125
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
715 : 1, 5, 11, 13, 55, 65, 143, 715
605 : 1, 5, 11, 55, 121, 605
925 : 1, 5, 25, 37, 185, 925
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 791,715,605,925, is 1.
Now, the common factors can be found like this.
791:7x 113
715:5x 11x 13
605:5x 11x 11
925:5x 5x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 11 = 275
Therefore, the value for common factors is 275.
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 = 316504313125/(1x275)
LCM = 316504313125/275
LCM = 1150924775
Thus, we can understand that the LCM of 791,715,605,925 is 1150924775.
