Given numbers are 893,645,479,489,442
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 893,645,479,489,442 is 19877261933490.
Find LCM of 893,645,479,489,442 with Prime Factorization
| 3 | 893, 645, 479, 489, 442 |
| 893, 215, 479, 163, 442 |
Multiply the prime numbers at the bottom and the left side.
3 x 893 x 215 x 479 x 163 x 442 = 19877261933490
Therefore, the lowest common multiple of 893,645,479,489,442 is 19877261933490.
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.
893 x 645 x 479 x 489 x 442 = 59631785800470
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.
893 : 1, 19, 47, 893
645 : 1, 3, 5, 15, 43, 129, 215, 645
479 : 1, 479
489 : 1, 3, 163, 489
442 : 1, 2, 13, 17, 26, 34, 221, 442
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 893,645,479,489,442, is 1.
Now, the common factors can be found like this.
893:19x 47
645:3x 5x 43
479:479
489:3x 163
442:2x 13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 59631785800470/(1x3)
LCM = 59631785800470/3
LCM = 19877261933490
Thus, we can understand that the LCM of 893,645,479,489,442 is 19877261933490.
