Given numbers are 561,885,551,220,575
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,885,551,220,575 is 41946362700.
Find LCM of 561,885,551,220,575 with Prime Factorization
| 3 | 561, 885, 551, 220, 575 |
| 5 | 187, 295, 551, 220, 575 |
| 11 | 187, 59, 551, 44, 115 |
| 17, 59, 551, 4, 115 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 17 x 59 x 551 x 4 x 115 = 41946362700
Therefore, the lowest common multiple of 561,885,551,220,575 is 41946362700.
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 885 x 551 x 220 x 575 = 34605749227500
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
885 : 1, 3, 5, 15, 59, 177, 295, 885
551 : 1, 19, 29, 551
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
575 : 1, 5, 23, 25, 115, 575
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,885,551,220,575, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
885:3x 5x 59
551:19x 29
220:2x 2x 5x 11
575:5x 5x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 11 = 825
Therefore, the value for common factors is 825.
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 = 34605749227500/(1x825)
LCM = 34605749227500/825
LCM = 41946362700
Thus, we can understand that the LCM of 561,885,551,220,575 is 41946362700.
