Given numbers are 782,646,499,775
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 782,646,499,775 is 5745960050.
Find LCM of 782,646,499,775 with Prime Factorization
| 2 | 782, 646, 499, 775 |
| 17 | 391, 323, 499, 775 |
| 23, 19, 499, 775 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 23 x 19 x 499 x 775 = 5745960050
Therefore, the lowest common multiple of 782,646,499,775 is 5745960050.
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.
782 x 646 x 499 x 775 = 195362641700
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.
782 : 1, 2, 17, 23, 34, 46, 391, 782
646 : 1, 2, 17, 19, 34, 38, 323, 646
499 : 1, 499
775 : 1, 5, 25, 31, 155, 775
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,646,499,775, is 1.
Now, the common factors can be found like this.
782:2x 17x 23
646:2x 17x 19
499:499
775:5x 5x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17 = 34
Therefore, the value for common factors is 34.
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 = 195362641700/(1x34)
LCM = 195362641700/34
LCM = 5745960050
Thus, we can understand that the LCM of 782,646,499,775 is 5745960050.
