Find LCM of 192,645,733,946,421 with Prime Factorization
| 2 | 192, 645, 733, 946, 421 |
| 3 | 96, 645, 733, 473, 421 |
| 43 | 32, 215, 733, 473, 421 |
| 32, 5, 733, 11, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 43 x 32 x 5 x 733 x 11 x 421 = 140125909440
Therefore, the lowest common multiple of 192,645,733,946,421 is 140125909440.
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.
192 x 645 x 733 x 946 x 421 = 36152484635520
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.
192 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 192
645 : 1, 3, 5, 15, 43, 129, 215, 645
733 : 1, 733
946 : 1, 2, 11, 22, 43, 86, 473, 946
421 : 1, 421
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 192,645,733,946,421, is 1.
Now, the common factors can be found like this.
192:2x 2x 2x 2x 2x 2x 3
645:3x 5x 43
733:733
946:2x 11x 43
421:421
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 43 = 258
Therefore, the value for common factors is 258.
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 = 36152484635520/(1x258)
LCM = 36152484635520/258
LCM = 140125909440
Thus, we can understand that the LCM of 192,645,733,946,421 is 140125909440.
