Find LCM of 828,548,144,785 with Prime Factorization
| 2 | 828, 548, 144, 785 |
| 2 | 414, 274, 72, 785 |
| 3 | 207, 137, 36, 785 |
| 3 | 69, 137, 12, 785 |
| 23, 137, 4, 785 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 23 x 137 x 4 x 785 = 356189040
Therefore, the lowest common multiple of 828,548,144,785 is 356189040.
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.
828 x 548 x 144 x 785 = 51291221760
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.
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
548 : 1, 2, 4, 137, 274, 548
144 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
785 : 1, 5, 157, 785
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 828,548,144,785, is 1.
Now, the common factors can be found like this.
828:2x 2x 3x 3x 23
548:2x 2x 137
144:2x 2x 2x 2x 3x 3
785:5x 157
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 3 = 144
Therefore, the value for common factors is 144.
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 = 51291221760/(1x144)
LCM = 51291221760/144
LCM = 356189040
Thus, we can understand that the LCM of 828,548,144,785 is 356189040.
