Find LCM of 373,720,645,486 with Prime Factorization
| 2 | 373, 720, 645, 486 |
| 3 | 373, 360, 645, 243 |
| 3 | 373, 120, 215, 81 |
| 5 | 373, 40, 215, 27 |
| 373, 8, 43, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 373 x 8 x 43 x 27 = 311798160
Therefore, the lowest common multiple of 373,720,645,486 is 311798160.
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.
373 x 720 x 645 x 486 = 84185503200
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.
373 : 1, 373
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
645 : 1, 3, 5, 15, 43, 129, 215, 645
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 373,720,645,486, is 1.
Now, the common factors can be found like this.
373:373
720:2x 2x 2x 2x 3x 3x 5
645:3x 5x 43
486:2x 3x 3x 3x 3x 3
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 3x 3x 5 = 270
Therefore, the value for common factors is 270.
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 = 84185503200/(1x270)
LCM = 84185503200/270
LCM = 311798160
Thus, we can understand that the LCM of 373,720,645,486 is 311798160.
