Given numbers are 851,858,794,163
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 851,858,794,163 is 47249254338.
Find LCM of 851,858,794,163 with Prime Factorization
| 2 | 851, 858, 794, 163 |
| 851, 429, 397, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 851 x 429 x 397 x 163 = 47249254338
Therefore, the lowest common multiple of 851,858,794,163 is 47249254338.
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.
851 x 858 x 794 x 163 = 94498508676
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.
851 : 1, 23, 37, 851
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
794 : 1, 2, 397, 794
163 : 1, 163
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 851,858,794,163, is 1.
Now, the common factors can be found like this.
851:23x 37
858:2x 3x 11x 13
794:2x 397
163:163
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 94498508676/(1x2)
LCM = 94498508676/2
LCM = 47249254338
Thus, we can understand that the LCM of 851,858,794,163 is 47249254338.
