Given numbers are 431,924,830,163,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 431,924,830,163,561 is 457966661460.
Find LCM of 431,924,830,163,561 with Prime Factorization
| 2 | 431, 924, 830, 163, 561 |
| 3 | 431, 462, 415, 163, 561 |
| 11 | 431, 154, 415, 163, 187 |
| 431, 14, 415, 163, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 431 x 14 x 415 x 163 x 17 = 457966661460
Therefore, the lowest common multiple of 431,924,830,163,561 is 457966661460.
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.
431 x 924 x 830 x 163 x 561 = 30225799656360
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.
431 : 1, 431
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
830 : 1, 2, 5, 10, 83, 166, 415, 830
163 : 1, 163
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,924,830,163,561, is 1.
Now, the common factors can be found like this.
431:431
924:2x 2x 3x 7x 11
830:2x 5x 83
163:163
561:3x 11x 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 3x 11 = 66
Therefore, the value for common factors is 66.
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 = 30225799656360/(1x66)
LCM = 30225799656360/66
LCM = 457966661460
Thus, we can understand that the LCM of 431,924,830,163,561 is 457966661460.
