Given numbers are 406,194,638,476
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 406,194,638,476 is 14728868.
Find LCM of 406,194,638,476 with Prime Factorization
| 2 | 406, 194, 638, 476 |
| 7 | 203, 97, 319, 238 |
| 29 | 29, 97, 319, 34 |
| 1, 97, 11, 34 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 29 x 1 x 97 x 11 x 34 = 14728868
Therefore, the lowest common multiple of 406,194,638,476 is 14728868.
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.
406 x 194 x 638 x 476 = 23919681632
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.
406 : 1, 2, 7, 14, 29, 58, 203, 406
194 : 1, 2, 97, 194
638 : 1, 2, 11, 22, 29, 58, 319, 638
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 406,194,638,476, is 2.
Now, the common factors can be found like this.
406:2x 7x 29
194:2x 97
638:2x 11x 29
476:2x 2x 7x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 7x 29 = 812
Therefore, the value for common factors is 812.
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 = 23919681632/(2x812)
LCM = 23919681632/1624
LCM = 14728868
Thus, we can understand that the LCM of 406,194,638,476 is 14728868.
