Given numbers are 480,491,777,494,921
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 480,491,777,494,921 is 4628687088480.
Find LCM of 480,491,777,494,921 with Prime Factorization
| 2 | 480, 491, 777, 494, 921 |
| 3 | 240, 491, 777, 247, 921 |
| 80, 491, 259, 247, 307 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 80 x 491 x 259 x 247 x 307 = 4628687088480
Therefore, the lowest common multiple of 480,491,777,494,921 is 4628687088480.
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.
480 x 491 x 777 x 494 x 921 = 83316367592640
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.
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
491 : 1, 491
777 : 1, 3, 7, 21, 37, 111, 259, 777
494 : 1, 2, 13, 19, 26, 38, 247, 494
921 : 1, 3, 307, 921
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 480,491,777,494,921, is 1.
Now, the common factors can be found like this.
480:2x 2x 2x 2x 2x 3x 5
491:491
777:3x 7x 37
494:2x 13x 19
921:3x 307
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 = 83316367592640/(1x18)
LCM = 83316367592640/18
LCM = 4628687088480
Thus, we can understand that the LCM of 480,491,777,494,921 is 4628687088480.
