Given numbers are 724,845,494,248
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 724,845,494,248 is 720676840.
Find LCM of 724,845,494,248 with Prime Factorization
| 2 | 724, 845, 494, 248 |
| 2 | 362, 845, 247, 124 |
| 13 | 181, 845, 247, 62 |
| 181, 65, 19, 62 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 181 x 65 x 19 x 62 = 720676840
Therefore, the lowest common multiple of 724,845,494,248 is 720676840.
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.
724 x 845 x 494 x 248 = 74950391360
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.
724 : 1, 2, 4, 181, 362, 724
845 : 1, 5, 13, 65, 169, 845
494 : 1, 2, 13, 19, 26, 38, 247, 494
248 : 1, 2, 4, 8, 31, 62, 124, 248
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 724,845,494,248, is 1.
Now, the common factors can be found like this.
724:2x 2x 181
845:5x 13x 13
494:2x 13x 19
248:2x 2x 2x 31
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 13 = 104
Therefore, the value for common factors is 104.
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 = 74950391360/(1x104)
LCM = 74950391360/104
LCM = 720676840
Thus, we can understand that the LCM of 724,845,494,248 is 720676840.
