Given numbers are 645,305,603,930,735
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 645,305,603,930,735 is 24025552110.
Find LCM of 645,305,603,930,735 with Prime Factorization
| 3 | 645, 305, 603, 930, 735 |
| 5 | 215, 305, 201, 310, 245 |
| 43, 61, 201, 62, 49 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 43 x 61 x 201 x 62 x 49 = 24025552110
Therefore, the lowest common multiple of 645,305,603,930,735 is 24025552110.
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.
645 x 305 x 603 x 930 x 735 = 81086238371250
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.
645 : 1, 3, 5, 15, 43, 129, 215, 645
305 : 1, 5, 61, 305
603 : 1, 3, 9, 67, 201, 603
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
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 645,305,603,930,735, is 1.
Now, the common factors can be found like this.
645:3x 5x 43
305:5x 61
603:3x 3x 67
930:2x 3x 5x 31
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 5x 5x 5 = 3375
Therefore, the value for common factors is 3375.
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 = 81086238371250/(1x3375)
LCM = 81086238371250/3375
LCM = 24025552110
Thus, we can understand that the LCM of 645,305,603,930,735 is 24025552110.
