Given numbers are 493,989,492,857,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 493,989,492,857,561 is 2261423082468.
Find LCM of 493,989,492,857,561 with Prime Factorization
| 3 | 493, 989, 492, 857, 561 |
| 17 | 493, 989, 164, 857, 187 |
| 29, 989, 164, 857, 11 |
Multiply the prime numbers at the bottom and the left side.
3 x 17 x 29 x 989 x 164 x 857 x 11 = 2261423082468
Therefore, the lowest common multiple of 493,989,492,857,561 is 2261423082468.
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.
493 x 989 x 492 x 857 x 561 = 115332577205868
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.
493 : 1, 17, 29, 493
989 : 1, 23, 43, 989
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
857 : 1, 857
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 493,989,492,857,561, is 1.
Now, the common factors can be found like this.
493:17x 29
989:23x 43
492:2x 2x 3x 41
857:857
561:3x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 17 = 51
Therefore, the value for common factors is 51.
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 = 115332577205868/(1x51)
LCM = 115332577205868/51
LCM = 2261423082468
Thus, we can understand that the LCM of 493,989,492,857,561 is 2261423082468.
