Given numbers are 775,561,770,221,485
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 775,561,770,221,485 is 7675517850.
Find LCM of 775,561,770,221,485 with Prime Factorization
| 5 | 775, 561, 770, 221, 485 |
| 11 | 155, 561, 154, 221, 97 |
| 17 | 155, 51, 14, 221, 97 |
| 155, 3, 14, 13, 97 |
Multiply the prime numbers at the bottom and the left side.
5 x 11 x 17 x 155 x 3 x 14 x 13 x 97 = 7675517850
Therefore, the lowest common multiple of 775,561,770,221,485 is 7675517850.
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.
775 x 561 x 770 x 221 x 485 = 35883045948750
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.
775 : 1, 5, 25, 31, 155, 775
561 : 1, 3, 11, 17, 33, 51, 187, 561
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
221 : 1, 13, 17, 221
485 : 1, 5, 97, 485
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 775,561,770,221,485, is 1.
Now, the common factors can be found like this.
775:5x 5x 31
561:3x 11x 17
770:2x 5x 7x 11
221:13x 17
485:5x 97
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 17 = 4675
Therefore, the value for common factors is 4675.
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 = 35883045948750/(1x4675)
LCM = 35883045948750/4675
LCM = 7675517850
Thus, we can understand that the LCM of 775,561,770,221,485 is 7675517850.
