Given numbers are 775,123,861,687
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 775,123,861,687 is 152805975.
Find LCM of 775,123,861,687 with Prime Factorization
3 | 775, 123, 861, 687 |
41 | 775, 41, 287, 229 |
775, 1, 7, 229 |
Multiply the prime numbers at the bottom and the left side.
3 x 41 x 775 x 1 x 7 x 229 = 152805975
Therefore, the lowest common multiple of 775,123,861,687 is 152805975.
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.
775 x 123 x 861 x 687 = 56385404775
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.
775 : 1, 5, 25, 31, 155, 775
123 : 1, 3, 41, 123
861 : 1, 3, 7, 21, 41, 123, 287, 861
687 : 1, 3, 229, 687
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 775,123,861,687, is 1.
Now, the common factors can be found like this.
775:5x 5x 31
123:3x 41
861:3x 7x 41
687:3x 229
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 41 = 369
Therefore, the value for common factors is 369.
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 = 56385404775/(1x369)
LCM = 56385404775/369
LCM = 152805975
Thus, we can understand that the LCM of 775,123,861,687 is 152805975.
