Given numbers are 987,665,377,557,369
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 987,665,377,557,369 is 2421823085955.
Find LCM of 987,665,377,557,369 with Prime Factorization
| 3 | 987, 665, 377, 557, 369 |
| 7 | 329, 665, 377, 557, 123 |
| 47, 95, 377, 557, 123 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 47 x 95 x 377 x 557 x 123 = 2421823085955
Therefore, the lowest common multiple of 987,665,377,557,369 is 2421823085955.
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.
987 x 665 x 377 x 557 x 369 = 50858284805055
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.
987 : 1, 3, 7, 21, 47, 141, 329, 987
665 : 1, 5, 7, 19, 35, 95, 133, 665
377 : 1, 13, 29, 377
557 : 1, 557
369 : 1, 3, 9, 41, 123, 369
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 987,665,377,557,369, is 1.
Now, the common factors can be found like this.
987:3x 7x 47
665:5x 7x 19
377:13x 29
557:557
369:3x 3x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7 = 21
Therefore, the value for common factors is 21.
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 = 50858284805055/(1x21)
LCM = 50858284805055/21
LCM = 2421823085955
Thus, we can understand that the LCM of 987,665,377,557,369 is 2421823085955.
