The LCM of 128,923,169,568 is 1535872.
Find LCM of 128,923,169,568 with Prime Factorization
2 | 128, 923, 169, 568 |
2 | 64, 923, 169, 284 |
2 | 32, 923, 169, 142 |
13 | 16, 923, 169, 71 |
71 | 16, 71, 13, 71 |
16, 1, 13, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 13 x 71 x 16 x 1 x 13 x 1 = 1535872
Therefore, the lowest common multiple of 128,923,169,568 is 1535872.
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.
128 x 923 x 169 x 568 = 11340878848
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.
128 : 1, 2, 4, 8, 16, 32, 64, 128
923 : 1, 13, 71, 923
169 : 1, 13, 169
568 : 1, 2, 4, 8, 71, 142, 284, 568
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,923,169,568, is 1.
Now, the common factors can be found like this.
128:2x 2x 2x 2x 2x 2x 2
923:13x 71
169:13x 13
568:2x 2x 2x 71
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 13x 71 = 7384
Therefore, the value for common factors is 7384.
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 = 11340878848/(1x7384)
LCM = 11340878848/7384
LCM = 1535872
Thus, we can understand that the LCM of 128,923,169,568 is 1535872.
