The LCM of 421,792,729,627 is 513151848.
Find LCM of 421,792,729,627 with Prime Factorization
| 3 | 421, 792, 729, 627 |
| 3 | 421, 264, 243, 209 |
| 11 | 421, 88, 81, 209 |
| 421, 8, 81, 19 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 11 x 421 x 8 x 81 x 19 = 513151848
Therefore, the lowest common multiple of 421,792,729,627 is 513151848.
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.
421 x 792 x 729 x 627 = 152406098856
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.
421 : 1, 421
792 : 1, 2, 3, 4, 6, 8, 9, 11, 12, 18, 22, 24, 33, 36, 44, 66, 72, 88, 99, 132, 198, 264, 396, 792
729 : 1, 3, 9, 27, 81, 243, 729
627 : 1, 3, 11, 19, 33, 57, 209, 627
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,792,729,627, is 1.
Now, the common factors can be found like this.
421:421
792:2x 2x 2x 3x 3x 11
729:3x 3x 3x 3x 3x 3
627:3x 11x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 11 = 297
Therefore, the value for common factors is 297.
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 = 152406098856/(1x297)
LCM = 152406098856/297
LCM = 513151848
Thus, we can understand that the LCM of 421,792,729,627 is 513151848.
