Given numbers are 766,654,387,643
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 766,654,387,643 is 20776730454.
Find LCM of 766,654,387,643 with Prime Factorization
| 2 | 766, 654, 387, 643 |
| 3 | 383, 327, 387, 643 |
| 383, 109, 129, 643 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 383 x 109 x 129 x 643 = 20776730454
Therefore, the lowest common multiple of 766,654,387,643 is 20776730454.
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.
766 x 654 x 387 x 643 = 124660382724
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.
766 : 1, 2, 383, 766
654 : 1, 2, 3, 6, 109, 218, 327, 654
387 : 1, 3, 9, 43, 129, 387
643 : 1, 643
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 766,654,387,643, is 1.
Now, the common factors can be found like this.
766:2x 383
654:2x 3x 109
387:3x 3x 43
643:643
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 124660382724/(1x6)
LCM = 124660382724/6
LCM = 20776730454
Thus, we can understand that the LCM of 766,654,387,643 is 20776730454.
