Find LCM of 561,198,786,235,555 with Prime Factorization
2 | 561, 198, 786, 235, 555 |
3 | 561, 99, 393, 235, 555 |
5 | 187, 33, 131, 235, 185 |
11 | 187, 33, 131, 47, 37 |
17, 3, 131, 47, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 17 x 3 x 131 x 47 x 37 = 3834025470
Therefore, the lowest common multiple of 561,198,786,235,555 is 3834025470.
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.
561 x 198 x 786 x 235 x 555 = 11387055645900
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
786 : 1, 2, 3, 6, 131, 262, 393, 786
235 : 1, 5, 47, 235
555 : 1, 3, 5, 15, 37, 111, 185, 555
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,198,786,235,555, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
198:2x 3x 3x 11
786:2x 3x 131
235:5x 47
555:3x 5x 37
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 3x 5x 11 = 2970
Therefore, the value for common factors is 2970.
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 = 11387055645900/(1x2970)
LCM = 11387055645900/2970
LCM = 3834025470
Thus, we can understand that the LCM of 561,198,786,235,555 is 3834025470.
