Find LCM of 321,272,884,705,245 with Prime Factorization
2 | 321, 272, 884, 705, 245 |
2 | 321, 136, 442, 705, 245 |
3 | 321, 68, 221, 705, 245 |
5 | 107, 68, 221, 235, 245 |
17 | 107, 68, 221, 47, 49 |
107, 4, 13, 47, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 17 x 107 x 4 x 13 x 47 x 49 = 13070169840
Therefore, the lowest common multiple of 321,272,884,705,245 is 13070169840.
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.
321 x 272 x 884 x 705 x 245 = 13331573236800
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.
321 : 1, 3, 107, 321
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
705 : 1, 3, 5, 15, 47, 141, 235, 705
245 : 1, 5, 7, 35, 49, 245
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,272,884,705,245, is 1.
Now, the common factors can be found like this.
321:3x 107
272:2x 2x 2x 2x 17
884:2x 2x 13x 17
705:3x 5x 47
245:5x 7x 7
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 3x 5x 17 = 1020
Therefore, the value for common factors is 1020.
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 = 13331573236800/(1x1020)
LCM = 13331573236800/1020
LCM = 13070169840
Thus, we can understand that the LCM of 321,272,884,705,245 is 13070169840.
