Given numbers are 2,990,210,966
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 2,990,210,966 is 159390.
Find LCM of 2,990,210,966 with Prime Factorization
| 2 | 2, 990, 210, 966 |
| 3 | 1, 495, 105, 483 |
| 5 | 1, 165, 35, 161 |
| 7 | 1, 33, 7, 161 |
| 1, 33, 1, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 1 x 33 x 1 x 23 = 159390
Therefore, the lowest common multiple of 2,990,210,966 is 159390.
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.
2 x 990 x 210 x 966 = 401662800
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.
2 : 1, 2
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
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 2,990,210,966, is 2.
Now, the common factors can be found like this.
2:2
990:2x 3x 3x 5x 11
210:2x 3x 5x 7
966:2x 3x 7x 23
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 3x 3x 5x 7 = 1260
Therefore, the value for common factors is 1260.
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 = 401662800/(2x1260)
LCM = 401662800/2520
LCM = 159390
Thus, we can understand that the LCM of 2,990,210,966 is 159390.
