Given numbers are 470,395,401,385,331
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 470,395,401,385,331 is 379479256310.
Find LCM of 470,395,401,385,331 with Prime Factorization
| 5 | 470, 395, 401, 385, 331 |
| 94, 79, 401, 77, 331 |
Multiply the prime numbers at the bottom and the left side.
5 x 94 x 79 x 401 x 77 x 331 = 379479256310
Therefore, the lowest common multiple of 470,395,401,385,331 is 379479256310.
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.
470 x 395 x 401 x 385 x 331 = 9486981407750
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.
470 : 1, 2, 5, 10, 47, 94, 235, 470
395 : 1, 5, 79, 395
401 : 1, 401
385 : 1, 5, 7, 11, 35, 55, 77, 385
331 : 1, 331
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 470,395,401,385,331, is 1.
Now, the common factors can be found like this.
470:2x 5x 47
395:5x 79
401:401
385:5x 7x 11
331:331
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5 = 25
Therefore, the value for common factors is 25.
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 = 9486981407750/(1x25)
LCM = 9486981407750/25
LCM = 379479256310
Thus, we can understand that the LCM of 470,395,401,385,331 is 379479256310.
