Given numbers are 626,855,729,938
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 626,855,729,938 is 20332852470.
Find LCM of 626,855,729,938 with Prime Factorization
| 2 | 626, 855, 729, 938 |
| 3 | 313, 855, 729, 469 |
| 3 | 313, 285, 243, 469 |
| 313, 95, 81, 469 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 313 x 95 x 81 x 469 = 20332852470
Therefore, the lowest common multiple of 626,855,729,938 is 20332852470.
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.
626 x 855 x 729 x 938 = 365991344460
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.
626 : 1, 2, 313, 626
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
729 : 1, 3, 9, 27, 81, 243, 729
938 : 1, 2, 7, 14, 67, 134, 469, 938
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 626,855,729,938, is 1.
Now, the common factors can be found like this.
626:2x 313
855:3x 3x 5x 19
729:3x 3x 3x 3x 3x 3
938:2x 7x 67
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 3 = 18
Therefore, the value for common factors is 18.
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 = 365991344460/(1x18)
LCM = 365991344460/18
LCM = 20332852470
Thus, we can understand that the LCM of 626,855,729,938 is 20332852470.
