Given numbers are 422,326,429,690,138
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 422,326,429,690,138 is 3393557310.
Find LCM of 422,326,429,690,138 with Prime Factorization
2 | 422, 326, 429, 690, 138 |
3 | 211, 163, 429, 345, 69 |
23 | 211, 163, 143, 115, 23 |
211, 163, 143, 5, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 211 x 163 x 143 x 5 x 1 = 3393557310
Therefore, the lowest common multiple of 422,326,429,690,138 is 3393557310.
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.
422 x 326 x 429 x 690 x 138 = 5619730905360
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.
422 : 1, 2, 211, 422
326 : 1, 2, 163, 326
429 : 1, 3, 11, 13, 33, 39, 143, 429
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
138 : 1, 2, 3, 6, 23, 46, 69, 138
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,326,429,690,138, is 1.
Now, the common factors can be found like this.
422:2x 211
326:2x 163
429:3x 11x 13
690:2x 3x 5x 23
138:2x 3x 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 2x 3x 3x 23 = 1656
Therefore, the value for common factors is 1656.
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 = 5619730905360/(1x1656)
LCM = 5619730905360/1656
LCM = 3393557310
Thus, we can understand that the LCM of 422,326,429,690,138 is 3393557310.
