Given numbers are 561,818,874,683,621
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,818,874,683,621 is 1232709704622.
Find LCM of 561,818,874,683,621 with Prime Factorization
2 | 561, 818, 874, 683, 621 |
3 | 561, 409, 437, 683, 621 |
23 | 187, 409, 437, 683, 207 |
187, 409, 19, 683, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 187 x 409 x 19 x 683 x 9 = 1232709704622
Therefore, the lowest common multiple of 561,818,874,683,621 is 1232709704622.
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.
561 x 818 x 874 x 683 x 621 = 170113939237836
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
818 : 1, 2, 409, 818
874 : 1, 2, 19, 23, 38, 46, 437, 874
683 : 1, 683
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,818,874,683,621, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
818:2x 409
874:2x 19x 23
683:683
621:3x 3x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 23 = 138
Therefore, the value for common factors is 138.
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 = 170113939237836/(1x138)
LCM = 170113939237836/138
LCM = 1232709704622
Thus, we can understand that the LCM of 561,818,874,683,621 is 1232709704622.
