Given numbers are 306,243,851,765
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 306,243,851,765 is 35154810.
Find LCM of 306,243,851,765 with Prime Factorization
| 3 | 306, 243, 851, 765 |
| 3 | 102, 81, 851, 255 |
| 17 | 34, 27, 851, 85 |
| 2, 27, 851, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 17 x 2 x 27 x 851 x 5 = 35154810
Therefore, the lowest common multiple of 306,243,851,765 is 35154810.
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.
306 x 243 x 851 x 765 = 48408173370
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.
306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306
243 : 1, 3, 9, 27, 81, 243
851 : 1, 23, 37, 851
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 306,243,851,765, is 1.
Now, the common factors can be found like this.
306:2x 3x 3x 17
243:3x 3x 3x 3x 3
851:23x 37
765:3x 3x 5x 17
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 17 = 1377
Therefore, the value for common factors is 1377.
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 = 48408173370/(1x1377)
LCM = 48408173370/1377
LCM = 35154810
Thus, we can understand that the LCM of 306,243,851,765 is 35154810.
