Given numbers are 391,185,238,493
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 391,185,238,493 is 29368010.
Find LCM of 391,185,238,493 with Prime Factorization
| 17 | 391, 185, 238, 493 |
| 23, 185, 14, 29 |
Multiply the prime numbers at the bottom and the left side.
17 x 23 x 185 x 14 x 29 = 29368010
Therefore, the lowest common multiple of 391,185,238,493 is 29368010.
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.
391 x 185 x 238 x 493 = 8487354890
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.
391 : 1, 17, 23, 391
185 : 1, 5, 37, 185
238 : 1, 2, 7, 14, 17, 34, 119, 238
493 : 1, 17, 29, 493
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 391,185,238,493, is 1.
Now, the common factors can be found like this.
391:17x 23
185:5x 37
238:2x 7x 17
493:17x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17x 17 = 289
Therefore, the value for common factors is 289.
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 = 8487354890/(1x289)
LCM = 8487354890/289
LCM = 29368010
Thus, we can understand that the LCM of 391,185,238,493 is 29368010.
