Given numbers are 646,527,618,961
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 646,527,618,961 is 191829054.
Find LCM of 646,527,618,961 with Prime Factorization
| 2 | 646, 527, 618, 961 |
| 17 | 323, 527, 309, 961 |
| 31 | 19, 31, 309, 961 |
| 19, 1, 309, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 31 x 19 x 1 x 309 x 31 = 191829054
Therefore, the lowest common multiple of 646,527,618,961 is 191829054.
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 527 x 618 x 961 = 202187822916
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
527 : 1, 17, 31, 527
618 : 1, 2, 3, 6, 103, 206, 309, 618
961 : 1, 31, 961
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,527,618,961, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
527:17x 31
618:2x 3x 103
961:31x 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 17x 31 = 1054
Therefore, the value for common factors is 1054.
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 = 202187822916/(1x1054)
LCM = 202187822916/1054
LCM = 191829054
Thus, we can understand that the LCM of 646,527,618,961 is 191829054.
