Given numbers are 123,938,653,878
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 123,938,653,878 is 33073918458.
Find LCM of 123,938,653,878 with Prime Factorization
| 2 | 123, 938, 653, 878 |
| 123, 469, 653, 439 |
Multiply the prime numbers at the bottom and the left side.
2 x 123 x 469 x 653 x 439 = 33073918458
Therefore, the lowest common multiple of 123,938,653,878 is 33073918458.
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.
123 x 938 x 653 x 878 = 66147836916
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.
123 : 1, 3, 41, 123
938 : 1, 2, 7, 14, 67, 134, 469, 938
653 : 1, 653
878 : 1, 2, 439, 878
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 123,938,653,878, is 1.
Now, the common factors can be found like this.
123:3x 41
938:2x 7x 67
653:653
878:2x 439
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 = 66147836916/(1x2)
LCM = 66147836916/2
LCM = 33073918458
Thus, we can understand that the LCM of 123,938,653,878 is 33073918458.
