Find LCM of 847,675,939,189 with Prime Factorization
| 3 | 847, 675, 939, 189 |
| 3 | 847, 225, 313, 63 |
| 3 | 847, 75, 313, 21 |
| 7 | 847, 25, 313, 7 |
| 121, 25, 313, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 7 x 121 x 25 x 313 x 1 = 178949925
Therefore, the lowest common multiple of 847,675,939,189 is 178949925.
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.
847 x 675 x 939 x 189 = 101464607475
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.
847 : 1, 7, 11, 77, 121, 847
675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
939 : 1, 3, 313, 939
189 : 1, 3, 7, 9, 21, 27, 63, 189
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 847,675,939,189, is 1.
Now, the common factors can be found like this.
847:7x 11x 11
675:3x 3x 3x 5x 5
939:3x 313
189:3x 3x 3x 7
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 7 = 567
Therefore, the value for common factors is 567.
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 = 101464607475/(1x567)
LCM = 101464607475/567
LCM = 178949925
Thus, we can understand that the LCM of 847,675,939,189 is 178949925.
