Find LCM of 138,912,984,847,473 with Prime Factorization
| 2 | 138, 912, 984, 847, 473 |
| 2 | 69, 456, 492, 847, 473 |
| 2 | 69, 228, 246, 847, 473 |
| 3 | 69, 114, 123, 847, 473 |
| 11 | 23, 38, 41, 847, 473 |
| 23, 38, 41, 77, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 11 x 23 x 38 x 41 x 77 x 43 = 31322642736
Therefore, the lowest common multiple of 138,912,984,847,473 is 31322642736.
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.
138 x 912 x 984 x 847 x 473 = 49615066093824
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.
138 : 1, 2, 3, 6, 23, 46, 69, 138
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
847 : 1, 7, 11, 77, 121, 847
473 : 1, 11, 43, 473
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 138,912,984,847,473, is 1.
Now, the common factors can be found like this.
138:2x 3x 23
912:2x 2x 2x 2x 3x 19
984:2x 2x 2x 3x 41
847:7x 11x 11
473:11x 43
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 3x 11 = 1584
Therefore, the value for common factors is 1584.
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 = 49615066093824/(1x1584)
LCM = 49615066093824/1584
LCM = 31322642736
Thus, we can understand that the LCM of 138,912,984,847,473 is 31322642736.
