Given numbers are 397,978,627,656,775
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 397,978,627,656,775 is 20627718394800.
Find LCM of 397,978,627,656,775 with Prime Factorization
| 2 | 397, 978, 627, 656, 775 |
| 3 | 397, 489, 627, 328, 775 |
| 397, 163, 209, 328, 775 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 397 x 163 x 209 x 328 x 775 = 20627718394800
Therefore, the lowest common multiple of 397,978,627,656,775 is 20627718394800.
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.
397 x 978 x 627 x 656 x 775 = 123766310368800
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.
397 : 1, 397
978 : 1, 2, 3, 6, 163, 326, 489, 978
627 : 1, 3, 11, 19, 33, 57, 209, 627
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
775 : 1, 5, 25, 31, 155, 775
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,978,627,656,775, is 1.
Now, the common factors can be found like this.
397:397
978:2x 3x 163
627:3x 11x 19
656:2x 2x 2x 2x 41
775:5x 5x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 123766310368800/(1x6)
LCM = 123766310368800/6
LCM = 20627718394800
Thus, we can understand that the LCM of 397,978,627,656,775 is 20627718394800.
