Given numbers are 488,856,144,331,721
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 488,856,144,331,721 is 224305211088.
Find LCM of 488,856,144,331,721 with Prime Factorization
| 2 | 488, 856, 144, 331, 721 |
| 2 | 244, 428, 72, 331, 721 |
| 2 | 122, 214, 36, 331, 721 |
| 61, 107, 18, 331, 721 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 61 x 107 x 18 x 331 x 721 = 224305211088
Therefore, the lowest common multiple of 488,856,144,331,721 is 224305211088.
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.
488 x 856 x 144 x 331 x 721 = 14355533509632
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.
488 : 1, 2, 4, 8, 61, 122, 244, 488
856 : 1, 2, 4, 8, 107, 214, 428, 856
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
331 : 1, 331
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 488,856,144,331,721, is 1.
Now, the common factors can be found like this.
488:2x 2x 2x 61
856:2x 2x 2x 107
144:2x 2x 2x 2x 3x 3
331:331
721:7x 103
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 2x 2x 2 = 64
Therefore, the value for common factors is 64.
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 = 14355533509632/(1x64)
LCM = 14355533509632/64
LCM = 224305211088
Thus, we can understand that the LCM of 488,856,144,331,721 is 224305211088.
