Given numbers are 853,644,253,943
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 853,644,253,943 is 247748732.
Find LCM of 853,644,253,943 with Prime Factorization
| 23 | 853, 644, 253, 943 |
| 853, 28, 11, 41 |
Multiply the prime numbers at the bottom and the left side.
23 x 853 x 28 x 11 x 41 = 247748732
Therefore, the lowest common multiple of 853,644,253,943 is 247748732.
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.
853 x 644 x 253 x 943 = 131059079228
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.
853 : 1, 853
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
253 : 1, 11, 23, 253
943 : 1, 23, 41, 943
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 853,644,253,943, is 1.
Now, the common factors can be found like this.
853:853
644:2x 2x 7x 23
253:11x 23
943:23x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23x 23 = 529
Therefore, the value for common factors is 529.
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 = 131059079228/(1x529)
LCM = 131059079228/529
LCM = 247748732
Thus, we can understand that the LCM of 853,644,253,943 is 247748732.
