Given numbers are 550,745,538,810
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 550,745,538,810 is 1785608550.
Find LCM of 550,745,538,810 with Prime Factorization
| 2 | 550, 745, 538, 810 |
| 5 | 275, 745, 269, 405 |
| 55, 149, 269, 81 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 55 x 149 x 269 x 81 = 1785608550
Therefore, the lowest common multiple of 550,745,538,810 is 1785608550.
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.
550 x 745 x 538 x 810 = 178560855000
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.
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
745 : 1, 5, 149, 745
538 : 1, 2, 269, 538
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 550,745,538,810, is 1.
Now, the common factors can be found like this.
550:2x 5x 5x 11
745:5x 149
538:2x 269
810:2x 3x 3x 3x 3x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 5x 5 = 100
Therefore, the value for common factors is 100.
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 = 178560855000/(1x100)
LCM = 178560855000/100
LCM = 1785608550
Thus, we can understand that the LCM of 550,745,538,810 is 1785608550.
