Given numbers are 994,422,786,357,161
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 994,422,786,357,161 is 32228355642.
Find LCM of 994,422,786,357,161 with Prime Factorization
| 2 | 994, 422, 786, 357, 161 |
| 3 | 497, 211, 393, 357, 161 |
| 7 | 497, 211, 131, 119, 161 |
| 71, 211, 131, 17, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 71 x 211 x 131 x 17 x 23 = 32228355642
Therefore, the lowest common multiple of 994,422,786,357,161 is 32228355642.
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.
994 x 422 x 786 x 357 x 161 = 18950273117496
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.
994 : 1, 2, 7, 14, 71, 142, 497, 994
422 : 1, 2, 211, 422
786 : 1, 2, 3, 6, 131, 262, 393, 786
357 : 1, 3, 7, 17, 21, 51, 119, 357
161 : 1, 7, 23, 161
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 994,422,786,357,161, is 1.
Now, the common factors can be found like this.
994:2x 7x 71
422:2x 211
786:2x 3x 131
357:3x 7x 17
161:7x 23
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 7x 7 = 588
Therefore, the value for common factors is 588.
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 = 18950273117496/(1x588)
LCM = 18950273117496/588
LCM = 32228355642
Thus, we can understand that the LCM of 994,422,786,357,161 is 32228355642.
