Given numbers are 240,555,806,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 240,555,806,561 is 669205680.
Find LCM of 240,555,806,561 with Prime Factorization
| 2 | 240, 555, 806, 561 |
| 3 | 120, 555, 403, 561 |
| 5 | 40, 185, 403, 187 |
| 8, 37, 403, 187 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 8 x 37 x 403 x 187 = 669205680
Therefore, the lowest common multiple of 240,555,806,561 is 669205680.
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.
240 x 555 x 806 x 561 = 60228511200
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.
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
555 : 1, 3, 5, 15, 37, 111, 185, 555
806 : 1, 2, 13, 26, 31, 62, 403, 806
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 240,555,806,561, is 1.
Now, the common factors can be found like this.
240:2x 2x 2x 2x 3x 5
555:3x 5x 37
806:2x 13x 31
561:3x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5 = 90
Therefore, the value for common factors is 90.
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 = 60228511200/(1x90)
LCM = 60228511200/90
LCM = 669205680
Thus, we can understand that the LCM of 240,555,806,561 is 669205680.
