Given numbers are 492,363,921,605
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 492,363,921,605 is 91381620.
Find LCM of 492,363,921,605 with Prime Factorization
| 3 | 492, 363, 921, 605 |
| 11 | 164, 121, 307, 605 |
| 11 | 164, 11, 307, 55 |
| 164, 1, 307, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 11 x 164 x 1 x 307 x 5 = 91381620
Therefore, the lowest common multiple of 492,363,921,605 is 91381620.
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 363 x 921 x 605 = 99514584180
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
363 : 1, 3, 11, 33, 121, 363
921 : 1, 3, 307, 921
605 : 1, 5, 11, 55, 121, 605
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 492,363,921,605, is 1.
Now, the common factors can be found like this.
492:2x 2x 3x 41
363:3x 11x 11
921:3x 307
605:5x 11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 11x 11 = 1089
Therefore, the value for common factors is 1089.
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 = 99514584180/(1x1089)
LCM = 99514584180/1089
LCM = 91381620
Thus, we can understand that the LCM of 492,363,921,605 is 91381620.
