Find LCM of 171,664,688,896,771 with Prime Factorization
| 2 | 171, 664, 688, 896, 771 |
| 2 | 171, 332, 344, 448, 771 |
| 2 | 171, 166, 172, 224, 771 |
| 2 | 171, 83, 86, 112, 771 |
| 3 | 171, 83, 43, 56, 771 |
| 57, 83, 43, 56, 257 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 57 x 83 x 43 x 56 x 257 = 140534771328
Therefore, the lowest common multiple of 171,664,688,896,771 is 140534771328.
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.
171 x 664 x 688 x 896 x 771 = 53965352189952
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.
171 : 1, 3, 9, 19, 57, 171
664 : 1, 2, 4, 8, 83, 166, 332, 664
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
771 : 1, 3, 257, 771
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 171,664,688,896,771, is 1.
Now, the common factors can be found like this.
171:3x 3x 19
664:2x 2x 2x 83
688:2x 2x 2x 2x 43
896:2x 2x 2x 2x 2x 2x 2x 7
771:3x 257
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 3 = 384
Therefore, the value for common factors is 384.
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 = 53965352189952/(1x384)
LCM = 53965352189952/384
LCM = 140534771328
Thus, we can understand that the LCM of 171,664,688,896,771 is 140534771328.
