Given numbers are 609,663,189,889
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 609,663,189,889 is 153835227.
Find LCM of 609,663,189,889 with Prime Factorization
| 3 | 609, 663, 189, 889 |
| 7 | 203, 221, 63, 889 |
| 29, 221, 9, 127 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 29 x 221 x 9 x 127 = 153835227
Therefore, the lowest common multiple of 609,663,189,889 is 153835227.
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.
609 x 663 x 189 x 889 = 67841335107
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.
609 : 1, 3, 7, 21, 29, 87, 203, 609
663 : 1, 3, 13, 17, 39, 51, 221, 663
189 : 1, 3, 7, 9, 21, 27, 63, 189
889 : 1, 7, 127, 889
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 609,663,189,889, is 1.
Now, the common factors can be found like this.
609:3x 7x 29
663:3x 13x 17
189:3x 3x 3x 7
889:7x 127
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 7x 7 = 441
Therefore, the value for common factors is 441.
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 = 67841335107/(1x441)
LCM = 67841335107/441
LCM = 153835227
Thus, we can understand that the LCM of 609,663,189,889 is 153835227.
