Given numbers are 281,807,481,645,735
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 281,807,481,645,735 is 1149104355945.
Find LCM of 281,807,481,645,735 with Prime Factorization
| 3 | 281, 807, 481, 645, 735 |
| 5 | 281, 269, 481, 215, 245 |
| 281, 269, 481, 43, 49 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 281 x 269 x 481 x 43 x 49 = 1149104355945
Therefore, the lowest common multiple of 281,807,481,645,735 is 1149104355945.
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.
281 x 807 x 481 x 645 x 735 = 51709696017525
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.
281 : 1, 281
807 : 1, 3, 269, 807
481 : 1, 13, 37, 481
645 : 1, 3, 5, 15, 43, 129, 215, 645
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 281,807,481,645,735, is 1.
Now, the common factors can be found like this.
281:281
807:3x 269
481:13x 37
645:3x 5x 43
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 5 = 45
Therefore, the value for common factors is 45.
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 = 51709696017525/(1x45)
LCM = 51709696017525/45
LCM = 1149104355945
Thus, we can understand that the LCM of 281,807,481,645,735 is 1149104355945.
