Given numbers are 851,286,322,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 851,286,322,781 is 120962842.
Find LCM of 851,286,322,781 with Prime Factorization
| 2 | 851, 286, 322, 781 |
| 11 | 851, 143, 161, 781 |
| 23 | 851, 13, 161, 71 |
| 37, 13, 7, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 23 x 37 x 13 x 7 x 71 = 120962842
Therefore, the lowest common multiple of 851,286,322,781 is 120962842.
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 286 x 322 x 781 = 61207198052
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
286 : 1, 2, 11, 13, 22, 26, 143, 286
322 : 1, 2, 7, 14, 23, 46, 161, 322
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 851,286,322,781, is 1.
Now, the common factors can be found like this.
851:23x 37
286:2x 11x 13
322:2x 7x 23
781:11x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 23 = 506
Therefore, the value for common factors is 506.
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 = 61207198052/(1x506)
LCM = 61207198052/506
LCM = 120962842
Thus, we can understand that the LCM of 851,286,322,781 is 120962842.
