Given numbers are 990,186,836,245
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 990,186,836,245 is 57144780.
Find LCM of 990,186,836,245 with Prime Factorization
| 2 | 990, 186, 836, 245 |
| 3 | 495, 93, 418, 245 |
| 5 | 165, 31, 418, 245 |
| 11 | 33, 31, 418, 49 |
| 3, 31, 38, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 3 x 31 x 38 x 49 = 57144780
Therefore, the lowest common multiple of 990,186,836,245 is 57144780.
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.
990 x 186 x 836 x 245 = 37715554800
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.
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
186 : 1, 2, 3, 6, 31, 62, 93, 186
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
245 : 1, 5, 7, 35, 49, 245
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,186,836,245, is 1.
Now, the common factors can be found like this.
990:2x 3x 3x 5x 11
186:2x 3x 31
836:2x 2x 11x 19
245:5x 7x 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 3x 5x 11 = 660
Therefore, the value for common factors is 660.
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 = 37715554800/(1x660)
LCM = 37715554800/660
LCM = 57144780
Thus, we can understand that the LCM of 990,186,836,245 is 57144780.
