Find LCM of 573,208,688,128 with Prime Factorization
| 2 | 573, 208, 688, 128 |
| 2 | 573, 104, 344, 64 |
| 2 | 573, 52, 172, 32 |
| 2 | 573, 26, 86, 16 |
| 573, 13, 43, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 573 x 13 x 43 x 8 = 40999296
Therefore, the lowest common multiple of 573,208,688,128 is 40999296.
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.
573 x 208 x 688 x 128 = 10495819776
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.
573 : 1, 3, 191, 573
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
128 : 1, 2, 4, 8, 16, 32, 64, 128
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 573,208,688,128, is 1.
Now, the common factors can be found like this.
573:3x 191
208:2x 2x 2x 2x 13
688:2x 2x 2x 2x 43
128:2x 2x 2x 2x 2x 2x 2
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 2 = 256
Therefore, the value for common factors is 256.
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 = 10495819776/(1x256)
LCM = 10495819776/256
LCM = 40999296
Thus, we can understand that the LCM of 573,208,688,128 is 40999296.
