Given numbers are 398,252,978,547
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,252,978,547 is 4471245828.
Find LCM of 398,252,978,547 with Prime Factorization
2 | 398, 252, 978, 547 |
3 | 199, 126, 489, 547 |
199, 42, 163, 547 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 199 x 42 x 163 x 547 = 4471245828
Therefore, the lowest common multiple of 398,252,978,547 is 4471245828.
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.
398 x 252 x 978 x 547 = 53654949936
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.
398 : 1, 2, 199, 398
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
978 : 1, 2, 3, 6, 163, 326, 489, 978
547 : 1, 547
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,252,978,547, is 1.
Now, the common factors can be found like this.
398:2x 199
252:2x 2x 3x 3x 7
978:2x 3x 163
547:547
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 3 = 12
Therefore, the value for common factors is 12.
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 = 53654949936/(1x12)
LCM = 53654949936/12
LCM = 4471245828
Thus, we can understand that the LCM of 398,252,978,547 is 4471245828.
