Given numbers are 792,721,627,820
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 792,721,627,820 is 2224169640.
Find LCM of 792,721,627,820 with Prime Factorization
| 2 | 792, 721, 627, 820 |
| 2 | 396, 721, 627, 410 |
| 3 | 198, 721, 627, 205 |
| 11 | 66, 721, 209, 205 |
| 6, 721, 19, 205 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 6 x 721 x 19 x 205 = 2224169640
Therefore, the lowest common multiple of 792,721,627,820 is 2224169640.
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.
792 x 721 x 627 x 820 = 293590392480
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.
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
721 : 1, 7, 103, 721
627 : 1, 3, 11, 19, 33, 57, 209, 627
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 792,721,627,820, is 1.
Now, the common factors can be found like this.
792:2x 2x 2x 3x 3x 11
721:7x 103
627:3x 11x 19
820:2x 2x 5x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 11 = 132
Therefore, the value for common factors is 132.
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 = 293590392480/(1x132)
LCM = 293590392480/132
LCM = 2224169640
Thus, we can understand that the LCM of 792,721,627,820 is 2224169640.
