Find LCM of 966,621,397,315 with Prime Factorization
3 | 966, 621, 397, 315 |
3 | 322, 207, 397, 105 |
7 | 322, 69, 397, 35 |
23 | 46, 69, 397, 5 |
2, 3, 397, 5 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 23 x 2 x 3 x 397 x 5 = 17257590
Therefore, the lowest common multiple of 966,621,397,315 is 17257590.
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 621 x 397 x 315 = 75018743730
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
621 : 1, 3, 9, 23, 27, 69, 207, 621
397 : 1, 397
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 966,621,397,315, is 1.
Now, the common factors can be found like this.
966:2x 3x 7x 23
621:3x 3x 3x 23
397:397
315:3x 3x 5x 7
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 3x 7x 23 = 4347
Therefore, the value for common factors is 4347.
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 = 75018743730/(1x4347)
LCM = 75018743730/4347
LCM = 17257590
Thus, we can understand that the LCM of 966,621,397,315 is 17257590.
