Given numbers are 513,363,442,240
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 513,363,442,240 is 1097450640.
Find LCM of 513,363,442,240 with Prime Factorization
| 2 | 513, 363, 442, 240 |
| 3 | 513, 363, 221, 120 |
| 171, 121, 221, 40 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 171 x 121 x 221 x 40 = 1097450640
Therefore, the lowest common multiple of 513,363,442,240 is 1097450640.
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.
513 x 363 x 442 x 240 = 19754111520
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.
513 : 1, 3, 9, 19, 27, 57, 171, 513
363 : 1, 3, 11, 33, 121, 363
442 : 1, 2, 13, 17, 26, 34, 221, 442
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 513,363,442,240, is 1.
Now, the common factors can be found like this.
513:3x 3x 3x 19
363:3x 11x 11
442:2x 13x 17
240:2x 2x 2x 2x 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 3x 3 = 18
Therefore, the value for common factors is 18.
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 = 19754111520/(1x18)
LCM = 19754111520/18
LCM = 1097450640
Thus, we can understand that the LCM of 513,363,442,240 is 1097450640.
