Given numbers are 986,781,552,858,399
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 986,781,552,858,399 is 367478575464.
Find LCM of 986,781,552,858,399 with Prime Factorization
| 2 | 986, 781, 552, 858, 399 |
| 3 | 493, 781, 276, 429, 399 |
| 11 | 493, 781, 92, 143, 133 |
| 493, 71, 92, 13, 133 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 493 x 71 x 92 x 13 x 133 = 367478575464
Therefore, the lowest common multiple of 986,781,552,858,399 is 367478575464.
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.
986 x 781 x 552 x 858 x 399 = 145521515883744
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.
986 : 1, 2, 17, 29, 34, 58, 493, 986
781 : 1, 11, 71, 781
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
399 : 1, 3, 7, 19, 21, 57, 133, 399
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 986,781,552,858,399, is 1.
Now, the common factors can be found like this.
986:2x 17x 29
781:11x 71
552:2x 2x 2x 3x 23
858:2x 3x 11x 13
399:3x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 11 = 396
Therefore, the value for common factors is 396.
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 = 145521515883744/(1x396)
LCM = 145521515883744/396
LCM = 367478575464
Thus, we can understand that the LCM of 986,781,552,858,399 is 367478575464.
