Given numbers are 646,715,494,111
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 646,715,494,111 is 51269790.
Find LCM of 646,715,494,111 with Prime Factorization
| 2 | 646, 715, 494, 111 |
| 13 | 323, 715, 247, 111 |
| 19 | 323, 55, 19, 111 |
| 17, 55, 1, 111 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 19 x 17 x 55 x 1 x 111 = 51269790
Therefore, the lowest common multiple of 646,715,494,111 is 51269790.
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.
646 x 715 x 494 x 111 = 25327276260
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
715 : 1, 5, 11, 13, 55, 65, 143, 715
494 : 1, 2, 13, 19, 26, 38, 247, 494
111 : 1, 3, 37, 111
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,715,494,111, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
715:5x 11x 13
494:2x 13x 19
111:3x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 19 = 494
Therefore, the value for common factors is 494.
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 = 25327276260/(1x494)
LCM = 25327276260/494
LCM = 51269790
Thus, we can understand that the LCM of 646,715,494,111 is 51269790.
