Given numbers are 477,442,741,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 477,442,741,561 is 44064306.
Find LCM of 477,442,741,561 with Prime Factorization
| 3 | 477, 442, 741, 561 |
| 13 | 159, 442, 247, 187 |
| 17 | 159, 34, 19, 187 |
| 159, 2, 19, 11 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 17 x 159 x 2 x 19 x 11 = 44064306
Therefore, the lowest common multiple of 477,442,741,561 is 44064306.
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.
477 x 442 x 741 x 561 = 87643904634
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.
477 : 1, 3, 9, 53, 159, 477
442 : 1, 2, 13, 17, 26, 34, 221, 442
741 : 1, 3, 13, 19, 39, 57, 247, 741
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 477,442,741,561, is 1.
Now, the common factors can be found like this.
477:3x 3x 53
442:2x 13x 17
741:3x 13x 19
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.
3x 3x 13x 17 = 1989
Therefore, the value for common factors is 1989.
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 = 87643904634/(1x1989)
LCM = 87643904634/1989
LCM = 44064306
Thus, we can understand that the LCM of 477,442,741,561 is 44064306.
