Given numbers are 474,836,374,431,644
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 474,836,374,431,644 is 233725819404.
Find LCM of 474,836,374,431,644 with Prime Factorization
| 2 | 474, 836, 374, 431, 644 |
| 2 | 237, 418, 187, 431, 322 |
| 11 | 237, 209, 187, 431, 161 |
| 237, 19, 17, 431, 161 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 237 x 19 x 17 x 431 x 161 = 233725819404
Therefore, the lowest common multiple of 474,836,374,431,644 is 233725819404.
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.
474 x 836 x 374 x 431 x 644 = 41135744215104
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.
474 : 1, 2, 3, 6, 79, 158, 237, 474
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
374 : 1, 2, 11, 17, 22, 34, 187, 374
431 : 1, 431
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 474,836,374,431,644, is 1.
Now, the common factors can be found like this.
474:2x 3x 79
836:2x 2x 11x 19
374:2x 11x 17
431:431
644:2x 2x 7x 23
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 2x 11 = 176
Therefore, the value for common factors is 176.
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 = 41135744215104/(1x176)
LCM = 41135744215104/176
LCM = 233725819404
Thus, we can understand that the LCM of 474,836,374,431,644 is 233725819404.
