Given numbers are 629,646,386,731
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 629,646,386,731 is 198362698.
Find LCM of 629,646,386,731 with Prime Factorization
2 | 629, 646, 386, 731 |
17 | 629, 323, 193, 731 |
37, 19, 193, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 37 x 19 x 193 x 43 = 198362698
Therefore, the lowest common multiple of 629,646,386,731 is 198362698.
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 646 x 386 x 731 = 114653639444
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
646 : 1, 2, 17, 19, 34, 38, 323, 646
386 : 1, 2, 193, 386
731 : 1, 17, 43, 731
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 629,646,386,731, is 1.
Now, the common factors can be found like this.
629:17x 37
646:2x 17x 19
386:2x 193
731:17x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17x 17 = 578
Therefore, the value for common factors is 578.
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 = 114653639444/(1x578)
LCM = 114653639444/578
LCM = 198362698
Thus, we can understand that the LCM of 629,646,386,731 is 198362698.
