Given numbers are 998,655,655,241
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 998,655,655,241 is 157539290.
Find LCM of 998,655,655,241 with Prime Factorization
5 | 998, 655, 655, 241 |
131 | 998, 131, 131, 241 |
998, 1, 1, 241 |
Multiply the prime numbers at the bottom and the left side.
5 x 131 x 998 x 1 x 1 x 241 = 157539290
Therefore, the lowest common multiple of 998,655,655,241 is 157539290.
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 655 x 655 x 241 = 103188234950
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
655 : 1, 5, 131, 655
655 : 1, 5, 131, 655
241 : 1, 241
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 998,655,655,241, is 1.
Now, the common factors can be found like this.
998:2x 499
655:5x 131
655:5x 131
241:241
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 131 = 655
Therefore, the value for common factors is 655.
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 = 103188234950/(1x655)
LCM = 103188234950/655
LCM = 157539290
Thus, we can understand that the LCM of 998,655,655,241 is 157539290.
