Given numbers are 509,682,661,198,857
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 509,682,661,198,857 is 1769811235434.
Find LCM of 509,682,661,198,857 with Prime Factorization
2 | 509, 682, 661, 198, 857 |
11 | 509, 341, 661, 99, 857 |
509, 31, 661, 9, 857 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 509 x 31 x 661 x 9 x 857 = 1769811235434
Therefore, the lowest common multiple of 509,682,661,198,857 is 1769811235434.
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.
509 x 682 x 661 x 198 x 857 = 38935847179548
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.
509 : 1, 509
682 : 1, 2, 11, 22, 31, 62, 341, 682
661 : 1, 661
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
857 : 1, 857
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 509,682,661,198,857, is 1.
Now, the common factors can be found like this.
509:509
682:2x 11x 31
661:661
198:2x 3x 3x 11
857:857
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11 = 22
Therefore, the value for common factors is 22.
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 = 38935847179548/(1x22)
LCM = 38935847179548/22
LCM = 1769811235434
Thus, we can understand that the LCM of 509,682,661,198,857 is 1769811235434.
