Given numbers are 209,606,307,644
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 209,606,307,644 is 12520254516.
Find LCM of 209,606,307,644 with Prime Factorization
| 2 | 209, 606, 307, 644 |
| 209, 303, 307, 322 |
Multiply the prime numbers at the bottom and the left side.
2 x 209 x 303 x 307 x 322 = 12520254516
Therefore, the lowest common multiple of 209,606,307,644 is 12520254516.
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.
209 x 606 x 307 x 644 = 25040509032
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.
209 : 1, 11, 19, 209
606 : 1, 2, 3, 6, 101, 202, 303, 606
307 : 1, 307
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,606,307,644, is 1.
Now, the common factors can be found like this.
209:11x 19
606:2x 3x 101
307:307
644:2x 2x 7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 25040509032/(1x2)
LCM = 25040509032/2
LCM = 12520254516
Thus, we can understand that the LCM of 209,606,307,644 is 12520254516.
