Given numbers are 754,206,972,918
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 754,206,972,918 is 641643444.
Find LCM of 754,206,972,918 with Prime Factorization
| 2 | 754, 206, 972, 918 |
| 3 | 377, 103, 486, 459 |
| 3 | 377, 103, 162, 153 |
| 3 | 377, 103, 54, 51 |
| 377, 103, 18, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 377 x 103 x 18 x 17 = 641643444
Therefore, the lowest common multiple of 754,206,972,918 is 641643444.
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.
754 x 206 x 972 x 918 = 138594983904
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.
754 : 1, 2, 13, 26, 29, 58, 377, 754
206 : 1, 2, 103, 206
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 754,206,972,918, is 2.
Now, the common factors can be found like this.
754:2x 13x 29
206:2x 103
972:2x 2x 3x 3x 3x 3x 3
918:2x 3x 3x 3x 17
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 3 = 108
Therefore, the value for common factors is 108.
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 = 138594983904/(2x108)
LCM = 138594983904/216
LCM = 641643444
Thus, we can understand that the LCM of 754,206,972,918 is 641643444.
