Given numbers are 422,931,274,285,789
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 422,931,274,285,789 is 212338970130.
Find LCM of 422,931,274,285,789 with Prime Factorization
| 2 | 422, 931, 274, 285, 789 |
| 3 | 211, 931, 137, 285, 789 |
| 19 | 211, 931, 137, 95, 263 |
| 211, 49, 137, 5, 263 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 211 x 49 x 137 x 5 x 263 = 212338970130
Therefore, the lowest common multiple of 422,931,274,285,789 is 212338970130.
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 931 x 274 x 285 x 789 = 24206642594820
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
931 : 1, 7, 19, 49, 133, 931
274 : 1, 2, 137, 274
285 : 1, 3, 5, 15, 19, 57, 95, 285
789 : 1, 3, 263, 789
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 422,931,274,285,789, is 1.
Now, the common factors can be found like this.
422:2x 211
931:7x 7x 19
274:2x 137
285:3x 5x 19
789:3x 263
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 19 = 114
Therefore, the value for common factors is 114.
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 = 24206642594820/(1x114)
LCM = 24206642594820/114
LCM = 212338970130
Thus, we can understand that the LCM of 422,931,274,285,789 is 212338970130.
