Given numbers are 102,663,243,389,969
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 102,663,243,389,969 is 793837746.
Find LCM of 102,663,243,389,969 with Prime Factorization
| 3 | 102, 663, 243, 389, 969 |
| 17 | 34, 221, 81, 389, 323 |
| 2, 13, 81, 389, 19 |
Multiply the prime numbers at the bottom and the left side.
3 x 17 x 2 x 13 x 81 x 389 x 19 = 793837746
Therefore, the lowest common multiple of 102,663,243,389,969 is 793837746.
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.
102 x 663 x 243 x 389 x 969 = 6194315932038
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.
102 : 1, 2, 3, 6, 17, 34, 51, 102
663 : 1, 3, 13, 17, 39, 51, 221, 663
243 : 1, 3, 9, 27, 81, 243
389 : 1, 389
969 : 1, 3, 17, 19, 51, 57, 323, 969
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 102,663,243,389,969, is 1.
Now, the common factors can be found like this.
102:2x 3x 17
663:3x 13x 17
243:3x 3x 3x 3x 3
389:389
969:3x 17x 19
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 3x 17x 17 = 7803
Therefore, the value for common factors is 7803.
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 = 6194315932038/(1x7803)
LCM = 6194315932038/7803
LCM = 793837746
Thus, we can understand that the LCM of 102,663,243,389,969 is 793837746.
