Find LCM of 387,481,754,814,972 with Prime Factorization
| 2 | 387, 481, 754, 814, 972 |
| 3 | 387, 481, 377, 407, 486 |
| 3 | 129, 481, 377, 407, 162 |
| 13 | 43, 481, 377, 407, 54 |
| 37 | 43, 37, 29, 407, 54 |
| 43, 1, 29, 11, 54 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 13 x 37 x 43 x 1 x 29 x 11 x 54 = 6413136444
Therefore, the lowest common multiple of 387,481,754,814,972 is 6413136444.
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.
387 x 481 x 754 x 814 x 972 = 111049870664304
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.
387 : 1, 3, 9, 43, 129, 387
481 : 1, 13, 37, 481
754 : 1, 2, 13, 26, 29, 58, 377, 754
814 : 1, 2, 11, 22, 37, 74, 407, 814
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 387,481,754,814,972, is 1.
Now, the common factors can be found like this.
387:3x 3x 43
481:13x 37
754:2x 13x 29
814:2x 11x 37
972:2x 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 2x 3x 3x 13x 37 = 17316
Therefore, the value for common factors is 17316.
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 = 111049870664304/(1x17316)
LCM = 111049870664304/17316
LCM = 6413136444
Thus, we can understand that the LCM of 387,481,754,814,972 is 6413136444.
