Given numbers are 729,117,871,994
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 729,117,871,994 is 631149246.
Find LCM of 729,117,871,994 with Prime Factorization
| 3 | 729, 117, 871, 994 |
| 3 | 243, 39, 871, 994 |
| 13 | 81, 13, 871, 994 |
| 81, 1, 67, 994 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 13 x 81 x 1 x 67 x 994 = 631149246
Therefore, the lowest common multiple of 729,117,871,994 is 631149246.
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.
729 x 117 x 871 x 994 = 73844461782
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.
729 : 1, 3, 9, 27, 81, 243, 729
117 : 1, 3, 9, 13, 39, 117
871 : 1, 13, 67, 871
994 : 1, 2, 7, 14, 71, 142, 497, 994
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 729,117,871,994, is 1.
Now, the common factors can be found like this.
729:3x 3x 3x 3x 3x 3
117:3x 3x 13
871:13x 67
994:2x 7x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 13 = 117
Therefore, the value for common factors is 117.
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 = 73844461782/(1x117)
LCM = 73844461782/117
LCM = 631149246
Thus, we can understand that the LCM of 729,117,871,994 is 631149246.
