Find LCM of 128,308,785,768,323 with Prime Factorization
2 | 128, 308, 785, 768, 323 |
2 | 64, 154, 785, 384, 323 |
2 | 32, 77, 785, 192, 323 |
2 | 16, 77, 785, 96, 323 |
2 | 8, 77, 785, 48, 323 |
2 | 4, 77, 785, 24, 323 |
2 | 2, 77, 785, 12, 323 |
1, 77, 785, 6, 323 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 2 x 2 x 1 x 77 x 785 x 6 x 323 = 14994228480
Therefore, the lowest common multiple of 128,308,785,768,323 is 14994228480.
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 308 x 785 x 768 x 323 = 7677044981760
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
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
785 : 1, 5, 157, 785
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
323 : 1, 17, 19, 323
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 128,308,785,768,323, is 1.
Now, the common factors can be found like this.
128:2x 2x 2x 2x 2x 2x 2
308:2x 2x 7x 11
785:5x 157
768:2x 2x 2x 2x 2x 2x 2x 2x 3
323:17x 19
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 2x 2x 2x 2 = 512
Therefore, the value for common factors is 512.
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 = 7677044981760/(1x512)
LCM = 7677044981760/512
LCM = 14994228480
Thus, we can understand that the LCM of 128,308,785,768,323 is 14994228480.
