Given numbers are 484,921,670,720
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 484,921,670,720 is 1791971280.
Find LCM of 484,921,670,720 with Prime Factorization
| 2 | 484, 921, 670, 720 |
| 2 | 242, 921, 335, 360 |
| 3 | 121, 921, 335, 180 |
| 5 | 121, 307, 335, 60 |
| 121, 307, 67, 12 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 121 x 307 x 67 x 12 = 1791971280
Therefore, the lowest common multiple of 484,921,670,720 is 1791971280.
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.
484 x 921 x 670 x 720 = 215036553600
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.
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
921 : 1, 3, 307, 921
670 : 1, 2, 5, 10, 67, 134, 335, 670
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 484,921,670,720, is 1.
Now, the common factors can be found like this.
484:2x 2x 11x 11
921:3x 307
670:2x 5x 67
720:2x 2x 2x 2x 3x 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 = 215036553600/(1x120)
LCM = 215036553600/120
LCM = 1791971280
Thus, we can understand that the LCM of 484,921,670,720 is 1791971280.
