Find LCM of 921,672,855,856,890 with Prime Factorization
2 | 921, 672, 855, 856, 890 |
2 | 921, 336, 855, 428, 445 |
2 | 921, 168, 855, 214, 445 |
3 | 921, 84, 855, 107, 445 |
5 | 307, 28, 285, 107, 445 |
307, 28, 57, 107, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 307 x 28 x 57 x 107 x 89 = 559920402720
Therefore, the lowest common multiple of 921,672,855,856,890 is 559920402720.
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.
921 x 672 x 855 x 856 x 890 = 403142689958400
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.
921 : 1, 3, 307, 921
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
856 : 1, 2, 4, 8, 107, 214, 428, 856
890 : 1, 2, 5, 10, 89, 178, 445, 890
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,672,855,856,890, is 1.
Now, the common factors can be found like this.
921:3x 307
672:2x 2x 2x 2x 2x 3x 7
855:3x 3x 5x 19
856:2x 2x 2x 107
890:2x 5x 89
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 3x 3x 5 = 720
Therefore, the value for common factors is 720.
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 = 403142689958400/(1x720)
LCM = 403142689958400/720
LCM = 559920402720
Thus, we can understand that the LCM of 921,672,855,856,890 is 559920402720.
