Find LCM of 342,502,721,861,489 with Prime Factorization
2 | 342, 502, 721, 861, 489 |
3 | 171, 251, 721, 861, 489 |
7 | 57, 251, 721, 287, 163 |
57, 251, 103, 41, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 57 x 251 x 103 x 41 x 163 = 413624784006
Therefore, the lowest common multiple of 342,502,721,861,489 is 413624784006.
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.
342 x 502 x 721 x 861 x 489 = 52116722784756
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.
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
502 : 1, 2, 251, 502
721 : 1, 7, 103, 721
861 : 1, 3, 7, 21, 41, 123, 287, 861
489 : 1, 3, 163, 489
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 342,502,721,861,489, is 1.
Now, the common factors can be found like this.
342:2x 3x 3x 19
502:2x 251
721:7x 103
861:3x 7x 41
489:3x 163
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 3x 7 = 126
Therefore, the value for common factors is 126.
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 = 52116722784756/(1x126)
LCM = 52116722784756/126
LCM = 413624784006
Thus, we can understand that the LCM of 342,502,721,861,489 is 413624784006.
