Given numbers are 854,243,915,791
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 854,243,915,791 is 117249930.
Find LCM of 854,243,915,791 with Prime Factorization
3 | 854, 243, 915, 791 |
7 | 854, 81, 305, 791 |
61 | 122, 81, 305, 113 |
2, 81, 5, 113 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 61 x 2 x 81 x 5 x 113 = 117249930
Therefore, the lowest common multiple of 854,243,915,791 is 117249930.
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.
854 x 243 x 915 x 791 = 150197160330
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.
854 : 1, 2, 7, 14, 61, 122, 427, 854
243 : 1, 3, 9, 27, 81, 243
915 : 1, 3, 5, 15, 61, 183, 305, 915
791 : 1, 7, 113, 791
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 854,243,915,791, is 1.
Now, the common factors can be found like this.
854:2x 7x 61
243:3x 3x 3x 3x 3
915:3x 5x 61
791:7x 113
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 61 = 1281
Therefore, the value for common factors is 1281.
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 = 150197160330/(1x1281)
LCM = 150197160330/1281
LCM = 117249930
Thus, we can understand that the LCM of 854,243,915,791 is 117249930.
