The LCM of 854,435,957,986 is 69468630.
Find LCM of 854,435,957,986 with Prime Factorization
| 2 | 854, 435, 957, 986 |
| 3 | 427, 435, 957, 493 |
| 29 | 427, 145, 319, 493 |
| 427, 5, 11, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 29 x 427 x 5 x 11 x 17 = 69468630
Therefore, the lowest common multiple of 854,435,957,986 is 69468630.
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 435 x 957 x 986 = 350538706980
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
435 : 1, 3, 5, 15, 29, 87, 145, 435
957 : 1, 3, 11, 29, 33, 87, 319, 957
986 : 1, 2, 17, 29, 34, 58, 493, 986
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 854,435,957,986, is 1.
Now, the common factors can be found like this.
854:2x 7x 61
435:3x 5x 29
957:3x 11x 29
986:2x 17x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 29x 29 = 5046
Therefore, the value for common factors is 5046.
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 = 350538706980/(1x5046)
LCM = 350538706980/5046
LCM = 69468630
Thus, we can understand that the LCM of 854,435,957,986 is 69468630.
