Find LCM of 851,285,684,147,855 with Prime Factorization
3 | 851, 285, 684, 147, 855 |
3 | 851, 95, 228, 49, 285 |
5 | 851, 95, 76, 49, 95 |
19 | 851, 19, 76, 49, 19 |
851, 1, 4, 49, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 19 x 851 x 1 x 4 x 49 x 1 = 142610580
Therefore, the lowest common multiple of 851,285,684,147,855 is 142610580.
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.
851 x 285 x 684 x 147 x 855 = 20850379848900
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.
851 : 1, 23, 37, 851
285 : 1, 3, 5, 15, 19, 57, 95, 285
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
147 : 1, 3, 7, 21, 49, 147
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 851,285,684,147,855, is 1.
Now, the common factors can be found like this.
851:23x 37
285:3x 5x 19
684:2x 2x 3x 3x 19
147:3x 7x 7
855:3x 3x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 5x 19x 19 = 146205
Therefore, the value for common factors is 146205.
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 = 20850379848900/(1x146205)
LCM = 20850379848900/146205
LCM = 142610580
Thus, we can understand that the LCM of 851,285,684,147,855 is 142610580.
