Given numbers are 638,134,946,455,410
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 638,134,946,455,410 is 34289345090.
Find LCM of 638,134,946,455,410 with Prime Factorization
| 2 | 638, 134, 946, 455, 410 |
| 5 | 319, 67, 473, 455, 205 |
| 11 | 319, 67, 473, 91, 41 |
| 29, 67, 43, 91, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 29 x 67 x 43 x 91 x 41 = 34289345090
Therefore, the lowest common multiple of 638,134,946,455,410 is 34289345090.
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.
638 x 134 x 946 x 455 x 410 = 15087311839600
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.
638 : 1, 2, 11, 22, 29, 58, 319, 638
134 : 1, 2, 67, 134
946 : 1, 2, 11, 22, 43, 86, 473, 946
455 : 1, 5, 7, 13, 35, 65, 91, 455
410 : 1, 2, 5, 10, 41, 82, 205, 410
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,134,946,455,410, is 1.
Now, the common factors can be found like this.
638:2x 11x 29
134:2x 67
946:2x 11x 43
455:5x 7x 13
410:2x 5x 41
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 2x 5x 11 = 440
Therefore, the value for common factors is 440.
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 = 15087311839600/(1x440)
LCM = 15087311839600/440
LCM = 34289345090
Thus, we can understand that the LCM of 638,134,946,455,410 is 34289345090.
