Given numbers are 231,874,605,860
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 231,874,605,860 is 954958620.
Find LCM of 231,874,605,860 with Prime Factorization
| 2 | 231, 874, 605, 860 |
| 5 | 231, 437, 605, 430 |
| 11 | 231, 437, 121, 86 |
| 21, 437, 11, 86 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 21 x 437 x 11 x 86 = 954958620
Therefore, the lowest common multiple of 231,874,605,860 is 954958620.
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.
231 x 874 x 605 x 860 = 105045448200
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.
231 : 1, 3, 7, 11, 21, 33, 77, 231
874 : 1, 2, 19, 23, 38, 46, 437, 874
605 : 1, 5, 11, 55, 121, 605
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 231,874,605,860, is 1.
Now, the common factors can be found like this.
231:3x 7x 11
874:2x 19x 23
605:5x 11x 11
860:2x 2x 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 5x 11 = 110
Therefore, the value for common factors is 110.
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 = 105045448200/(1x110)
LCM = 105045448200/110
LCM = 954958620
Thus, we can understand that the LCM of 231,874,605,860 is 954958620.
