Given numbers are 492,656,424,940
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 492,656,424,940 is 24511440.
Find LCM of 492,656,424,940 with Prime Factorization
| 2 | 492, 656, 424, 940 |
| 2 | 246, 328, 212, 470 |
| 2 | 123, 164, 106, 235 |
| 41 | 123, 82, 53, 235 |
| 3, 2, 53, 235 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 41 x 3 x 2 x 53 x 235 = 24511440
Therefore, the lowest common multiple of 492,656,424,940 is 24511440.
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.
492 x 656 x 424 x 940 = 128636037120
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.
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
424 : 1, 2, 4, 8, 53, 106, 212, 424
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
4 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 492,656,424,940, is 4.
Now, the common factors can be found like this.
492:2x 2x 3x 41
656:2x 2x 2x 2x 41
424:2x 2x 2x 53
940:2x 2x 5x 47
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 2x 41 = 1312
Therefore, the value for common factors is 1312.
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 = 128636037120/(4x1312)
LCM = 128636037120/5248
LCM = 24511440
Thus, we can understand that the LCM of 492,656,424,940 is 24511440.
