Given numbers are 279,921,644,729,735
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 279,921,644,729,735 is 156380108220.
Find LCM of 279,921,644,729,735 with Prime Factorization
| 3 | 279, 921, 644, 729, 735 |
| 3 | 93, 307, 644, 243, 245 |
| 7 | 31, 307, 644, 81, 245 |
| 31, 307, 92, 81, 35 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 31 x 307 x 92 x 81 x 35 = 156380108220
Therefore, the lowest common multiple of 279,921,644,729,735 is 156380108220.
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.
279 x 921 x 644 x 729 x 735 = 88667521360740
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.
279 : 1, 3, 9, 31, 93, 279
921 : 1, 3, 307, 921
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
729 : 1, 3, 9, 27, 81, 243, 729
735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 279,921,644,729,735, is 1.
Now, the common factors can be found like this.
279:3x 3x 31
921:3x 307
644:2x 2x 7x 23
729:3x 3x 3x 3x 3x 3
735:3x 5x 7x 7
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 3x 7 = 567
Therefore, the value for common factors is 567.
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 = 88667521360740/(1x567)
LCM = 88667521360740/567
LCM = 156380108220
Thus, we can understand that the LCM of 279,921,644,729,735 is 156380108220.
