Find LCM of 231,877,538,420,561 with Prime Factorization
| 2 | 231, 877, 538, 420, 561 |
| 3 | 231, 877, 269, 210, 561 |
| 7 | 77, 877, 269, 70, 187 |
| 11 | 11, 877, 269, 10, 187 |
| 1, 877, 269, 10, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 11 x 1 x 877 x 269 x 10 x 17 = 18528607020
Therefore, the lowest common multiple of 231,877,538,420,561 is 18528607020.
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.
231 x 877 x 538 x 420 x 561 = 25680649329720
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.
231 : 1, 3, 7, 11, 21, 33, 77, 231
877 : 1, 877
538 : 1, 2, 269, 538
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 231,877,538,420,561, is 1.
Now, the common factors can be found like this.
231:3x 7x 11
877:877
538:2x 269
420:2x 2x 3x 5x 7
561:3x 11x 17
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 7x 11 = 1386
Therefore, the value for common factors is 1386.
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 = 25680649329720/(1x1386)
LCM = 25680649329720/1386
LCM = 18528607020
Thus, we can understand that the LCM of 231,877,538,420,561 is 18528607020.
