Given numbers are 842,243,738,138,627
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 842,243,738,138,627 is 40325182722.
Find LCM of 842,243,738,138,627 with Prime Factorization
| 2 | 842, 243, 738, 138, 627 |
| 3 | 421, 243, 369, 69, 627 |
| 3 | 421, 81, 123, 23, 209 |
| 421, 27, 41, 23, 209 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 421 x 27 x 41 x 23 x 209 = 40325182722
Therefore, the lowest common multiple of 842,243,738,138,627 is 40325182722.
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.
842 x 243 x 738 x 138 x 627 = 13065359201928
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.
842 : 1, 2, 421, 842
243 : 1, 3, 9, 27, 81, 243
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
138 : 1, 2, 3, 6, 23, 46, 69, 138
627 : 1, 3, 11, 19, 33, 57, 209, 627
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 842,243,738,138,627, is 1.
Now, the common factors can be found like this.
842:2x 421
243:3x 3x 3x 3x 3
738:2x 3x 3x 41
138:2x 3x 23
627:3x 11x 19
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 3x 3 = 324
Therefore, the value for common factors is 324.
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 = 13065359201928/(1x324)
LCM = 13065359201928/324
LCM = 40325182722
Thus, we can understand that the LCM of 842,243,738,138,627 is 40325182722.
