Given numbers are 248,610,780,310,442
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 248,610,780,310,442 is 50149320.
Find LCM of 248,610,780,310,442 with Prime Factorization
| 2 | 248, 610, 780, 310, 442 |
| 2 | 124, 305, 390, 155, 221 |
| 5 | 62, 305, 195, 155, 221 |
| 13 | 62, 61, 39, 31, 221 |
| 31 | 62, 61, 3, 31, 17 |
| 2, 61, 3, 1, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 13 x 31 x 2 x 61 x 3 x 1 x 17 = 50149320
Therefore, the lowest common multiple of 248,610,780,310,442 is 50149320.
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.
248 x 610 x 780 x 310 x 442 = 16168140768000
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.
248 : 1, 2, 4, 8, 31, 62, 124, 248
610 : 1, 2, 5, 10, 61, 122, 305, 610
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
310 : 1, 2, 5, 10, 31, 62, 155, 310
442 : 1, 2, 13, 17, 26, 34, 221, 442
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 248,610,780,310,442, is 2.
Now, the common factors can be found like this.
248:2x 2x 2x 31
610:2x 5x 61
780:2x 2x 3x 5x 13
310:2x 5x 31
442:2x 13x 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 2x 2x 2x 5x 5x 13x 31 = 161200
Therefore, the value for common factors is 161200.
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 = 16168140768000/(2x161200)
LCM = 16168140768000/322400
LCM = 50149320
Thus, we can understand that the LCM of 248,610,780,310,442 is 50149320.
