Find LCM of 804,400,785,48 with Prime Factorization
| 2 | 804, 400, 785, 48 |
| 2 | 402, 200, 785, 24 |
| 2 | 201, 100, 785, 12 |
| 2 | 201, 50, 785, 6 |
| 3 | 201, 25, 785, 3 |
| 5 | 67, 25, 785, 1 |
| 67, 5, 157, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 5 x 67 x 5 x 157 x 1 = 12622800
Therefore, the lowest common multiple of 804,400,785,48 is 12622800.
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.
804 x 400 x 785 x 48 = 12117888000
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.
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
785 : 1, 5, 157, 785
48 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 804,400,785,48, is 1.
Now, the common factors can be found like this.
804:2x 2x 3x 67
400:2x 2x 2x 2x 5x 5
785:5x 157
48:2x 2x 2x 2x 3
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 2x 3x 5 = 960
Therefore, the value for common factors is 960.
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 = 12117888000/(1x960)
LCM = 12117888000/960
LCM = 12622800
Thus, we can understand that the LCM of 804,400,785,48 is 12622800.
