Given numbers are 966,630,981,247
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 966,630,981,247 is 390114270.
Find LCM of 966,630,981,247 with Prime Factorization
| 2 | 966, 630, 981, 247 |
| 3 | 483, 315, 981, 247 |
| 3 | 161, 105, 327, 247 |
| 7 | 161, 35, 109, 247 |
| 23, 5, 109, 247 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 23 x 5 x 109 x 247 = 390114270
Therefore, the lowest common multiple of 966,630,981,247 is 390114270.
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.
966 x 630 x 981 x 247 = 147463194060
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.
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
981 : 1, 3, 9, 109, 327, 981
247 : 1, 13, 19, 247
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 966,630,981,247, is 1.
Now, the common factors can be found like this.
966:2x 3x 7x 23
630:2x 3x 3x 5x 7
981:3x 3x 109
247:13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 7 = 378
Therefore, the value for common factors is 378.
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 = 147463194060/(1x378)
LCM = 147463194060/378
LCM = 390114270
Thus, we can understand that the LCM of 966,630,981,247 is 390114270.
