Given numbers are 972,798,828,381
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 972,798,828,381 is 377615196.
Find LCM of 972,798,828,381 with Prime Factorization
| 2 | 972, 798, 828, 381 |
| 2 | 486, 399, 414, 381 |
| 3 | 243, 399, 207, 381 |
| 3 | 81, 133, 69, 127 |
| 27, 133, 23, 127 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 27 x 133 x 23 x 127 = 377615196
Therefore, the lowest common multiple of 972,798,828,381 is 377615196.
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.
972 x 798 x 828 x 381 = 244694647008
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.
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
381 : 1, 3, 127, 381
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,798,828,381, is 3.
Now, the common factors can be found like this.
972:2x 2x 3x 3x 3x 3x 3
798:2x 3x 7x 19
828:2x 2x 3x 3x 23
381:3x 127
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 2x 3x 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 244694647008/(3x216)
LCM = 244694647008/648
LCM = 377615196
Thus, we can understand that the LCM of 972,798,828,381 is 377615196.
