Given numbers are 551,394,978,398
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 551,394,978,398 is 21125634234.
Find LCM of 551,394,978,398 with Prime Factorization
2 | 551, 394, 978, 398 |
551, 197, 489, 199 |
Multiply the prime numbers at the bottom and the left side.
2 x 551 x 197 x 489 x 199 = 21125634234
Therefore, the lowest common multiple of 551,394,978,398 is 21125634234.
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.
551 x 394 x 978 x 398 = 84502536936
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.
551 : 1, 19, 29, 551
394 : 1, 2, 197, 394
978 : 1, 2, 3, 6, 163, 326, 489, 978
398 : 1, 2, 199, 398
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 551,394,978,398, is 1.
Now, the common factors can be found like this.
551:19x 29
394:2x 197
978:2x 3x 163
398:2x 199
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 84502536936/(1x4)
LCM = 84502536936/4
LCM = 21125634234
Thus, we can understand that the LCM of 551,394,978,398 is 21125634234.
