Given numbers are 612,561,383,663
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 612,561,383,663 is 33518628.
Find LCM of 612,561,383,663 with Prime Factorization
| 3 | 612, 561, 383, 663 |
| 17 | 204, 187, 383, 221 |
| 12, 11, 383, 13 |
Multiply the prime numbers at the bottom and the left side.
3 x 17 x 12 x 11 x 383 x 13 = 33518628
Therefore, the lowest common multiple of 612,561,383,663 is 33518628.
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.
612 x 561 x 383 x 663 = 87181951428
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.
612 : 1, 2, 3, 4, 6, 9, 12, 17, 18, 34, 36, 51, 68, 102, 153, 204, 306, 612
561 : 1, 3, 11, 17, 33, 51, 187, 561
383 : 1, 383
663 : 1, 3, 13, 17, 39, 51, 221, 663
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 612,561,383,663, is 1.
Now, the common factors can be found like this.
612:2x 2x 3x 3x 17
561:3x 11x 17
383:383
663:3x 13x 17
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 17x 17 = 2601
Therefore, the value for common factors is 2601.
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 = 87181951428/(1x2601)
LCM = 87181951428/2601
LCM = 33518628
Thus, we can understand that the LCM of 612,561,383,663 is 33518628.
