Find LCM of 630,482,684,990 with Prime Factorization
2 | 630, 482, 684, 990 |
3 | 315, 241, 342, 495 |
3 | 105, 241, 114, 165 |
5 | 35, 241, 38, 55 |
7, 241, 38, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 7 x 241 x 38 x 11 = 63464940
Therefore, the lowest common multiple of 630,482,684,990 is 63464940.
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.
630 x 482 x 684 x 990 = 205626405600
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.
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
482 : 1, 2, 241, 482
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
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 630,482,684,990, is 2.
Now, the common factors can be found like this.
630:2x 3x 3x 5x 7
482:2x 241
684:2x 2x 3x 3x 19
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 3x 3x 3x 3x 5 = 1620
Therefore, the value for common factors is 1620.
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 = 205626405600/(2x1620)
LCM = 205626405600/3240
LCM = 63464940
Thus, we can understand that the LCM of 630,482,684,990 is 63464940.
