Find LCM of 852,630,330,420 with Prime Factorization
2 | 852, 630, 330, 420 |
2 | 426, 315, 165, 210 |
3 | 213, 315, 165, 105 |
5 | 71, 35, 55, 105 |
7 | 71, 7, 11, 21 |
71, 1, 11, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 71 x 1 x 11 x 3 = 984060
Therefore, the lowest common multiple of 852,630,330,420 is 984060.
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.
852 x 630 x 330 x 420 = 74394936000
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.
852 : 1, 2, 3, 4, 6, 12, 71, 142, 213, 284, 426, 852
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
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
6 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 852,630,330,420, is 6.
Now, the common factors can be found like this.
852:2x 2x 3x 71
630:2x 3x 3x 5x 7
330:2x 3x 5x 11
420:2x 2x 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.
2x 2x 2x 3x 3x 5x 5x 7 = 12600
Therefore, the value for common factors is 12600.
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 = 74394936000/(6x12600)
LCM = 74394936000/75600
LCM = 984060
Thus, we can understand that the LCM of 852,630,330,420 is 984060.
