Given numbers are 397,823,775,823,756
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 397,823,775,823,756 is 191431692900.
Find LCM of 397,823,775,823,756 with Prime Factorization
| 823 | 397, 823, 775, 823, 756 |
| 397, 1, 775, 1, 756 |
Multiply the prime numbers at the bottom and the left side.
823 x 397 x 1 x 775 x 1 x 756 = 191431692900
Therefore, the lowest common multiple of 397,823,775,823,756 is 191431692900.
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.
397 x 823 x 775 x 823 x 756 = 157548283256700
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.
397 : 1, 397
823 : 1, 823
775 : 1, 5, 25, 31, 155, 775
823 : 1, 823
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,823,775,823,756, is 1.
Now, the common factors can be found like this.
397:397
823:823
775:5x 5x 31
823:823
756:2x 2x 3x 3x 3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
823 = 823
Therefore, the value for common factors is 823.
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 = 157548283256700/(1x823)
LCM = 157548283256700/823
LCM = 191431692900
Thus, we can understand that the LCM of 397,823,775,823,756 is 191431692900.
