Given numbers are 699,422,478,747,990
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 699,422,478,747,990 is 965493966690.
Find LCM of 699,422,478,747,990 with Prime Factorization
| 2 | 699, 422, 478, 747, 990 |
| 3 | 699, 211, 239, 747, 495 |
| 3 | 233, 211, 239, 249, 165 |
| 233, 211, 239, 83, 55 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 233 x 211 x 239 x 83 x 55 = 965493966690
Therefore, the lowest common multiple of 699,422,478,747,990 is 965493966690.
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.
699 x 422 x 478 x 747 x 990 = 104273348402520
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.
699 : 1, 3, 233, 699
422 : 1, 2, 211, 422
478 : 1, 2, 239, 478
747 : 1, 3, 9, 83, 249, 747
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 699,422,478,747,990, is 1.
Now, the common factors can be found like this.
699:3x 233
422:2x 211
478:2x 239
747:3x 3x 83
990:2x 3x 3x 5x 11
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 3x 3x 3 = 108
Therefore, the value for common factors is 108.
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 = 104273348402520/(1x108)
LCM = 104273348402520/108
LCM = 965493966690
Thus, we can understand that the LCM of 699,422,478,747,990 is 965493966690.
