Given numbers are 422,916,305
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 422,916,305 is 58949180.
Find LCM of 422,916,305 with Prime Factorization
| 2 | 422, 916, 305 |
| 211, 458, 305 |
Multiply the prime numbers at the bottom and the left side.
2 x 211 x 458 x 305 = 58949180
Therefore, the lowest common multiple of 422,916,305 is 58949180.
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 916 x 305 = 117898360
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
916 : 1, 2, 4, 229, 458, 916
305 : 1, 5, 61, 305
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,916,305, is 1.
Now, the common factors can be found like this.
422:2x 211
916:2x 2x 229
305:5x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 117898360/(1x2)
LCM = 117898360/2
LCM = 58949180
Thus, we can understand that the LCM of 422,916,305 is 58949180.
