Given numbers are 263,861,123,187
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 263,861,123,187 is 42344841.
Find LCM of 263,861,123,187 with Prime Factorization
| 3 | 263, 861, 123, 187 |
| 41 | 263, 287, 41, 187 |
| 263, 7, 1, 187 |
Multiply the prime numbers at the bottom and the left side.
3 x 41 x 263 x 7 x 1 x 187 = 42344841
Therefore, the lowest common multiple of 263,861,123,187 is 42344841.
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.
263 x 861 x 123 x 187 = 5208415443
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.
263 : 1, 263
861 : 1, 3, 7, 21, 41, 123, 287, 861
123 : 1, 3, 41, 123
187 : 1, 11, 17, 187
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 263,861,123,187, is 1.
Now, the common factors can be found like this.
263:263
861:3x 7x 41
123:3x 41
187:11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 41 = 123
Therefore, the value for common factors is 123.
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 = 5208415443/(1x123)
LCM = 5208415443/123
LCM = 42344841
Thus, we can understand that the LCM of 263,861,123,187 is 42344841.
