Given numbers are 609,916,988,210
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 609,916,988,210 is 688937340.
Find LCM of 609,916,988,210 with Prime Factorization
| 2 | 609, 916, 988, 210 |
| 2 | 609, 458, 494, 105 |
| 3 | 609, 229, 247, 105 |
| 7 | 203, 229, 247, 35 |
| 29, 229, 247, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 29 x 229 x 247 x 5 = 688937340
Therefore, the lowest common multiple of 609,916,988,210 is 688937340.
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 916 x 988 x 210 = 115741473120
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
916 : 1, 2, 4, 229, 458, 916
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 609,916,988,210, is 1.
Now, the common factors can be found like this.
609:3x 7x 29
916:2x 2x 229
988:2x 2x 13x 19
210:2x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 115741473120/(1x168)
LCM = 115741473120/168
LCM = 688937340
Thus, we can understand that the LCM of 609,916,988,210 is 688937340.
