Given numbers are 722,240,734,486
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 722,240,734,486 is 2575547280.
Find LCM of 722,240,734,486 with Prime Factorization
| 2 | 722, 240, 734, 486 |
| 3 | 361, 120, 367, 243 |
| 361, 40, 367, 81 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 361 x 40 x 367 x 81 = 2575547280
Therefore, the lowest common multiple of 722,240,734,486 is 2575547280.
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.
722 x 240 x 734 x 486 = 61813134720
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.
722 : 1, 2, 19, 38, 361, 722
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
734 : 1, 2, 367, 734
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 722,240,734,486, is 2.
Now, the common factors can be found like this.
722:2x 19x 19
240:2x 2x 2x 2x 3x 5
734:2x 367
486:2x 3x 3x 3x 3x 3
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 3 = 12
Therefore, the value for common factors is 12.
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 = 61813134720/(2x12)
LCM = 61813134720/24
LCM = 2575547280
Thus, we can understand that the LCM of 722,240,734,486 is 2575547280.
