Find LCM of 280,871,195,824,156 with Prime Factorization
| 2 | 280, 871, 195, 824, 156 |
| 2 | 140, 871, 195, 412, 78 |
| 2 | 70, 871, 195, 206, 39 |
| 3 | 35, 871, 195, 103, 39 |
| 5 | 35, 871, 65, 103, 13 |
| 13 | 7, 871, 13, 103, 13 |
| 7, 67, 1, 103, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 13 x 7 x 67 x 1 x 103 x 1 = 75358920
Therefore, the lowest common multiple of 280,871,195,824,156 is 75358920.
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.
280 x 871 x 195 x 824 x 156 = 6113115590400
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.
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
871 : 1, 13, 67, 871
195 : 1, 3, 5, 13, 15, 39, 65, 195
824 : 1, 2, 4, 8, 103, 206, 412, 824
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 280,871,195,824,156, is 1.
Now, the common factors can be found like this.
280:2x 2x 2x 5x 7
871:13x 67
195:3x 5x 13
824:2x 2x 2x 103
156:2x 2x 3x 13
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 2x 3x 5x 13x 13 = 81120
Therefore, the value for common factors is 81120.
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 = 6113115590400/(1x81120)
LCM = 6113115590400/81120
LCM = 75358920
Thus, we can understand that the LCM of 280,871,195,824,156 is 75358920.
