Given numbers are 481,544,984,728
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 481,544,984,728 is 225292704.
Find LCM of 481,544,984,728 with Prime Factorization
| 2 | 481, 544, 984, 728 |
| 2 | 481, 272, 492, 364 |
| 2 | 481, 136, 246, 182 |
| 13 | 481, 68, 123, 91 |
| 37, 68, 123, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 13 x 37 x 68 x 123 x 7 = 225292704
Therefore, the lowest common multiple of 481,544,984,728 is 225292704.
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.
481 x 544 x 984 x 728 = 187443529728
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.
481 : 1, 13, 37, 481
544 : 1, 2, 4, 8, 16, 17, 32, 34, 68, 136, 272, 544
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 481,544,984,728, is 1.
Now, the common factors can be found like this.
481:13x 37
544:2x 2x 2x 2x 2x 17
984:2x 2x 2x 3x 41
728:2x 2x 2x 7x 13
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 2x 13 = 832
Therefore, the value for common factors is 832.
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 = 187443529728/(1x832)
LCM = 187443529728/832
LCM = 225292704
Thus, we can understand that the LCM of 481,544,984,728 is 225292704.
