Given numbers are 629,242,646,847
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 629,242,646,847 is 20244994.
Find LCM of 629,242,646,847 with Prime Factorization
| 2 | 629, 242, 646, 847 |
| 11 | 629, 121, 323, 847 |
| 11 | 629, 11, 323, 77 |
| 17 | 629, 1, 323, 7 |
| 37, 1, 19, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 11 x 17 x 37 x 1 x 19 x 7 = 20244994
Therefore, the lowest common multiple of 629,242,646,847 is 20244994.
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.
629 x 242 x 646 x 847 = 83287905316
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.
629 : 1, 17, 37, 629
242 : 1, 2, 11, 22, 121, 242
646 : 1, 2, 17, 19, 34, 38, 323, 646
847 : 1, 7, 11, 77, 121, 847
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 629,242,646,847, is 1.
Now, the common factors can be found like this.
629:17x 37
242:2x 11x 11
646:2x 17x 19
847:7x 11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 11x 17 = 4114
Therefore, the value for common factors is 4114.
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 = 83287905316/(1x4114)
LCM = 83287905316/4114
LCM = 20244994
Thus, we can understand that the LCM of 629,242,646,847 is 20244994.
