Given numbers are 869,275,715,545
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 869,275,715,545 is 30784325.
Find LCM of 869,275,715,545 with Prime Factorization
| 5 | 869, 275, 715, 545 |
| 11 | 869, 55, 143, 109 |
| 79, 5, 13, 109 |
Multiply the prime numbers at the bottom and the left side.
5 x 11 x 79 x 5 x 13 x 109 = 30784325
Therefore, the lowest common multiple of 869,275,715,545 is 30784325.
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.
869 x 275 x 715 x 545 = 93122583125
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.
869 : 1, 11, 79, 869
275 : 1, 5, 11, 25, 55, 275
715 : 1, 5, 11, 13, 55, 65, 143, 715
545 : 1, 5, 109, 545
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 869,275,715,545, is 1.
Now, the common factors can be found like this.
869:11x 79
275:5x 5x 11
715:5x 11x 13
545:5x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 11x 11 = 3025
Therefore, the value for common factors is 3025.
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 = 93122583125/(1x3025)
LCM = 93122583125/3025
LCM = 30784325
Thus, we can understand that the LCM of 869,275,715,545 is 30784325.
