The LCM of 945,186,868,245 is 820260.
Find LCM of 945,186,868,245 with Prime Factorization
| 2 | 945, 186, 868, 245 |
| 3 | 945, 93, 434, 245 |
| 5 | 315, 31, 434, 245 |
| 7 | 63, 31, 434, 49 |
| 31 | 9, 31, 62, 7 |
| 9, 1, 2, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 31 x 9 x 1 x 2 x 7 = 820260
Therefore, the lowest common multiple of 945,186,868,245 is 820260.
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.
945 x 186 x 868 x 245 = 37379248200
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.
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
186 : 1, 2, 3, 6, 31, 62, 93, 186
868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868
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 945,186,868,245, is 1.
Now, the common factors can be found like this.
945:3x 3x 3x 5x 7
186:2x 3x 31
868:2x 2x 7x 31
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 3x 5x 7x 7x 31 = 45570
Therefore, the value for common factors is 45570.
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 = 37379248200/(1x45570)
LCM = 37379248200/45570
LCM = 820260
Thus, we can understand that the LCM of 945,186,868,245 is 820260.
