Given numbers are 998,548,463,274,690
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 998,548,463,274,690 is 43679855220.
Find LCM of 998,548,463,274,690 with Prime Factorization
| 2 | 998, 548, 463, 274, 690 |
| 137 | 499, 274, 463, 137, 345 |
| 499, 2, 463, 1, 345 |
Multiply the prime numbers at the bottom and the left side.
2 x 137 x 499 x 2 x 463 x 1 x 345 = 43679855220
Therefore, the lowest common multiple of 998,548,463,274,690 is 43679855220.
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.
998 x 548 x 463 x 274 x 690 = 47873121321120
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.
998 : 1, 2, 499, 998
548 : 1, 2, 4, 137, 274, 548
463 : 1, 463
274 : 1, 2, 137, 274
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 998,548,463,274,690, is 1.
Now, the common factors can be found like this.
998:2x 499
548:2x 2x 137
463:463
274:2x 137
690:2x 3x 5x 23
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 137 = 1096
Therefore, the value for common factors is 1096.
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 = 47873121321120/(1x1096)
LCM = 47873121321120/1096
LCM = 43679855220
Thus, we can understand that the LCM of 998,548,463,274,690 is 43679855220.
