Given numbers are 609,538,162,987,682
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 609,538,162,987,682 is 141780195018.
Find LCM of 609,538,162,987,682 with Prime Factorization
| 2 | 609, 538, 162, 987, 682 |
| 3 | 609, 269, 81, 987, 341 |
| 7 | 203, 269, 27, 329, 341 |
| 29, 269, 27, 47, 341 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 29 x 269 x 27 x 47 x 341 = 141780195018
Therefore, the lowest common multiple of 609,538,162,987,682 is 141780195018.
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.
609 x 538 x 162 x 987 x 682 = 35728609144536
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.
609 : 1, 3, 7, 21, 29, 87, 203, 609
538 : 1, 2, 269, 538
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
987 : 1, 3, 7, 21, 47, 141, 329, 987
682 : 1, 2, 11, 22, 31, 62, 341, 682
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 609,538,162,987,682, is 1.
Now, the common factors can be found like this.
609:3x 7x 29
538:2x 269
162:2x 3x 3x 3x 3
987:3x 7x 47
682:2x 11x 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 2x 3x 3x 7 = 252
Therefore, the value for common factors is 252.
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 = 35728609144536/(1x252)
LCM = 35728609144536/252
LCM = 141780195018
Thus, we can understand that the LCM of 609,538,162,987,682 is 141780195018.
