Given numbers are 385,895,972,438,215
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 385,895,972,438,215 is 210267107820.
Find LCM of 385,895,972,438,215 with Prime Factorization
| 2 | 385, 895, 972, 438, 215 |
| 3 | 385, 895, 486, 219, 215 |
| 5 | 385, 895, 162, 73, 215 |
| 77, 179, 162, 73, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 77 x 179 x 162 x 73 x 43 = 210267107820
Therefore, the lowest common multiple of 385,895,972,438,215 is 210267107820.
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.
385 x 895 x 972 x 438 x 215 = 31540066173000
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.
385 : 1, 5, 7, 11, 35, 55, 77, 385
895 : 1, 5, 179, 895
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
438 : 1, 2, 3, 6, 73, 146, 219, 438
215 : 1, 5, 43, 215
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 385,895,972,438,215, is 1.
Now, the common factors can be found like this.
385:5x 7x 11
895:5x 179
972:2x 2x 3x 3x 3x 3x 3
438:2x 3x 73
215:5x 43
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 5x 5 = 150
Therefore, the value for common factors is 150.
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 = 31540066173000/(1x150)
LCM = 31540066173000/150
LCM = 210267107820
Thus, we can understand that the LCM of 385,895,972,438,215 is 210267107820.
