Find LCM of 512,728,990,705,402 with Prime Factorization
2 | 512, 728, 990, 705, 402 |
2 | 256, 364, 495, 705, 201 |
2 | 128, 182, 495, 705, 201 |
3 | 64, 91, 495, 705, 201 |
5 | 64, 91, 165, 235, 67 |
64, 91, 33, 47, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 64 x 91 x 33 x 47 x 67 = 72625512960
Therefore, the lowest common multiple of 512,728,990,705,402 is 72625512960.
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.
512 x 728 x 990 x 705 x 402 = 104580738662400
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.
512 : 1, 2, 4, 8, 16, 32, 64, 128, 256, 512
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
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
705 : 1, 3, 5, 15, 47, 141, 235, 705
402 : 1, 2, 3, 6, 67, 134, 201, 402
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 512,728,990,705,402, is 1.
Now, the common factors can be found like this.
512:2x 2x 2x 2x 2x 2x 2x 2x 2
728:2x 2x 2x 7x 13
990:2x 3x 3x 5x 11
705:3x 5x 47
402:2x 3x 67
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 2x 2x 3x 3x 5 = 1440
Therefore, the value for common factors is 1440.
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 = 104580738662400/(1x1440)
LCM = 104580738662400/1440
LCM = 72625512960
Thus, we can understand that the LCM of 512,728,990,705,402 is 72625512960.
