Given numbers are 496,978,442,591,154
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 496,978,442,591,154 is 813092135856.
Find LCM of 496,978,442,591,154 with Prime Factorization
| 2 | 496, 978, 442, 591, 154 |
| 3 | 248, 489, 221, 591, 77 |
| 248, 163, 221, 197, 77 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 248 x 163 x 221 x 197 x 77 = 813092135856
Therefore, the lowest common multiple of 496,978,442,591,154 is 813092135856.
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.
496 x 978 x 442 x 591 x 154 = 19514211260544
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.
496 : 1, 2, 4, 8, 16, 31, 62, 124, 248, 496
978 : 1, 2, 3, 6, 163, 326, 489, 978
442 : 1, 2, 13, 17, 26, 34, 221, 442
591 : 1, 3, 197, 591
154 : 1, 2, 7, 11, 14, 22, 77, 154
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 496,978,442,591,154, is 1.
Now, the common factors can be found like this.
496:2x 2x 2x 2x 31
978:2x 3x 163
442:2x 13x 17
591:3x 197
154:2x 7x 11
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 3 = 24
Therefore, the value for common factors is 24.
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 = 19514211260544/(1x24)
LCM = 19514211260544/24
LCM = 813092135856
Thus, we can understand that the LCM of 496,978,442,591,154 is 813092135856.
