Given numbers are 162,900,638,175
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 162,900,638,175 is 18087300.
Find LCM of 162,900,638,175 with Prime Factorization
| 2 | 162, 900, 638, 175 |
| 3 | 81, 450, 319, 175 |
| 3 | 27, 150, 319, 175 |
| 5 | 9, 50, 319, 175 |
| 5 | 9, 10, 319, 35 |
| 9, 2, 319, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 5 x 9 x 2 x 319 x 7 = 18087300
Therefore, the lowest common multiple of 162,900,638,175 is 18087300.
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 900 x 638 x 175 = 16278570000
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
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
638 : 1, 2, 11, 22, 29, 58, 319, 638
175 : 1, 5, 7, 25, 35, 175
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 162,900,638,175, is 1.
Now, the common factors can be found like this.
162:2x 3x 3x 3x 3
900:2x 2x 3x 3x 5x 5
638:2x 11x 29
175:5x 5x 7
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 5x 5 = 900
Therefore, the value for common factors is 900.
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 = 16278570000/(1x900)
LCM = 16278570000/900
LCM = 18087300
Thus, we can understand that the LCM of 162,900,638,175 is 18087300.
