Given numbers are 162,724,818,905
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 162,724,818,905 is 119926980.
Find LCM of 162,724,818,905 with Prime Factorization
| 2 | 162, 724, 818, 905 |
| 181 | 81, 362, 409, 905 |
| 81, 2, 409, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 181 x 81 x 2 x 409 x 5 = 119926980
Therefore, the lowest common multiple of 162,724,818,905 is 119926980.
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.
162 x 724 x 818 x 905 = 86827133520
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.
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
724 : 1, 2, 4, 181, 362, 724
818 : 1, 2, 409, 818
905 : 1, 5, 181, 905
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 162,724,818,905, is 1.
Now, the common factors can be found like this.
162:2x 3x 3x 3x 3
724:2x 2x 181
818:2x 409
905:5x 181
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 181 = 724
Therefore, the value for common factors is 724.
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 = 86827133520/(1x724)
LCM = 86827133520/724
LCM = 119926980
Thus, we can understand that the LCM of 162,724,818,905 is 119926980.
