Find LCM of 685,567,972,171 with Prime Factorization
| 3 | 685, 567, 972, 171 |
| 3 | 685, 189, 324, 57 |
| 3 | 685, 63, 108, 19 |
| 3 | 685, 21, 36, 19 |
| 685, 7, 12, 19 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 3 x 685 x 7 x 12 x 19 = 88554060
Therefore, the lowest common multiple of 685,567,972,171 is 88554060.
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.
685 x 567 x 972 x 171 = 64555909740
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.
685 : 1, 5, 137, 685
567 : 1, 3, 7, 9, 21, 27, 63, 81, 189, 567
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
171 : 1, 3, 9, 19, 57, 171
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,567,972,171, is 1.
Now, the common factors can be found like this.
685:5x 137
567:3x 3x 3x 3x 7
972:2x 2x 3x 3x 3x 3x 3
171:3x 3x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 3x 3x 3 = 729
Therefore, the value for common factors is 729.
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 = 64555909740/(1x729)
LCM = 64555909740/729
LCM = 88554060
Thus, we can understand that the LCM of 685,567,972,171 is 88554060.
