Given numbers are 655,393,397,755
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 655,393,397,755 is 117795855.
Find LCM of 655,393,397,755 with Prime Factorization
| 5 | 655, 393, 397, 755 |
| 131 | 131, 393, 397, 151 |
| 1, 3, 397, 151 |
Multiply the prime numbers at the bottom and the left side.
5 x 131 x 1 x 3 x 397 x 151 = 117795855
Therefore, the lowest common multiple of 655,393,397,755 is 117795855.
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.
655 x 393 x 397 x 755 = 77156285025
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.
655 : 1, 5, 131, 655
393 : 1, 3, 131, 393
397 : 1, 397
755 : 1, 5, 151, 755
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,393,397,755, is 1.
Now, the common factors can be found like this.
655:5x 131
393:3x 131
397:397
755:5x 151
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 = 77156285025/(1x655)
LCM = 77156285025/655
LCM = 117795855
Thus, we can understand that the LCM of 655,393,397,755 is 117795855.
