Given numbers are 182,422,156,556
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 182,422,156,556 is 32027268.
Find LCM of 182,422,156,556 with Prime Factorization
| 2 | 182, 422, 156, 556 |
| 2 | 91, 211, 78, 278 |
| 13 | 91, 211, 39, 139 |
| 7, 211, 3, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 7 x 211 x 3 x 139 = 32027268
Therefore, the lowest common multiple of 182,422,156,556 is 32027268.
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.
182 x 422 x 156 x 556 = 6661671744
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.
182 : 1, 2, 7, 13, 14, 26, 91, 182
422 : 1, 2, 211, 422
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
556 : 1, 2, 4, 139, 278, 556
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 182,422,156,556, is 2.
Now, the common factors can be found like this.
182:2x 7x 13
422:2x 211
156:2x 2x 3x 13
556:2x 2x 139
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 13 = 104
Therefore, the value for common factors is 104.
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 = 6661671744/(2x104)
LCM = 6661671744/208
LCM = 32027268
Thus, we can understand that the LCM of 182,422,156,556 is 32027268.
