Given numbers are 807,124,318,690,990
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 807,124,318,690,990 is 20127177180.
Find LCM of 807,124,318,690,990 with Prime Factorization
| 2 | 807, 124, 318, 690, 990 |
| 3 | 807, 62, 159, 345, 495 |
| 5 | 269, 62, 53, 115, 165 |
| 269, 62, 53, 23, 33 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 269 x 62 x 53 x 23 x 33 = 20127177180
Therefore, the lowest common multiple of 807,124,318,690,990 is 20127177180.
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.
807 x 124 x 318 x 690 x 990 = 21737351354400
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.
807 : 1, 3, 269, 807
124 : 1, 2, 4, 31, 62, 124
318 : 1, 2, 3, 6, 53, 106, 159, 318
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
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 807,124,318,690,990, is 1.
Now, the common factors can be found like this.
807:3x 269
124:2x 2x 31
318:2x 3x 53
690:2x 3x 5x 23
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 2x 3x 3x 3x 5 = 1080
Therefore, the value for common factors is 1080.
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 = 21737351354400/(1x1080)
LCM = 21737351354400/1080
LCM = 20127177180
Thus, we can understand that the LCM of 807,124,318,690,990 is 20127177180.
