Given numbers are 606,372,992,990
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 606,372,992,990 is 49595040.
Find LCM of 606,372,992,990 with Prime Factorization
| 2 | 606, 372, 992, 990 |
| 2 | 303, 186, 496, 495 |
| 3 | 303, 93, 248, 495 |
| 31 | 101, 31, 248, 165 |
| 101, 1, 8, 165 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 31 x 101 x 1 x 8 x 165 = 49595040
Therefore, the lowest common multiple of 606,372,992,990 is 49595040.
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.
606 x 372 x 992 x 990 = 221392258560
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.
606 : 1, 2, 3, 6, 101, 202, 303, 606
372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 606,372,992,990, is 2.
Now, the common factors can be found like this.
606:2x 3x 101
372:2x 2x 3x 31
992:2x 2x 2x 2x 2x 31
990:2x 3x 3x 5x 11
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 3x 3x 31 = 2232
Therefore, the value for common factors is 2232.
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 = 221392258560/(2x2232)
LCM = 221392258560/4464
LCM = 49595040
Thus, we can understand that the LCM of 606,372,992,990 is 49595040.
