Given numbers are 729,760,841,120
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 729,760,841,120 is 465947640.
Find LCM of 729,760,841,120 with Prime Factorization
| 2 | 729, 760, 841, 120 |
| 2 | 729, 380, 841, 60 |
| 2 | 729, 190, 841, 30 |
| 3 | 729, 95, 841, 15 |
| 5 | 243, 95, 841, 5 |
| 243, 19, 841, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 243 x 19 x 841 x 1 = 465947640
Therefore, the lowest common multiple of 729,760,841,120 is 465947640.
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.
729 x 760 x 841 x 120 = 55913716800
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.
729 : 1, 3, 9, 27, 81, 243, 729
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
841 : 1, 29, 841
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 729,760,841,120, is 1.
Now, the common factors can be found like this.
729:3x 3x 3x 3x 3x 3
760:2x 2x 2x 5x 19
841:29x 29
120:2x 2x 2x 3x 5
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 2x 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 55913716800/(1x120)
LCM = 55913716800/120
LCM = 465947640
Thus, we can understand that the LCM of 729,760,841,120 is 465947640.
