Find LCM of 876,945,540,988 with Prime Factorization
| 2 | 876, 945, 540, 988 |
| 2 | 438, 945, 270, 494 |
| 3 | 219, 945, 135, 247 |
| 3 | 73, 315, 45, 247 |
| 3 | 73, 105, 15, 247 |
| 5 | 73, 35, 5, 247 |
| 73, 7, 1, 247 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 5 x 73 x 7 x 1 x 247 = 68157180
Therefore, the lowest common multiple of 876,945,540,988 is 68157180.
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.
876 x 945 x 540 x 988 = 441658526400
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.
876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 876,945,540,988, is 1.
Now, the common factors can be found like this.
876:2x 2x 3x 73
945:3x 3x 3x 5x 7
540:2x 2x 3x 3x 3x 5
988:2x 2x 13x 19
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 2x 3x 3x 3x 3x 5 = 6480
Therefore, the value for common factors is 6480.
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 = 441658526400/(1x6480)
LCM = 441658526400/6480
LCM = 68157180
Thus, we can understand that the LCM of 876,945,540,988 is 68157180.
