Find LCM of 804,136,788,529,690 with Prime Factorization
| 2 | 804, 136, 788, 529, 690 |
| 2 | 402, 68, 394, 529, 345 |
| 3 | 201, 34, 197, 529, 345 |
| 23 | 67, 34, 197, 529, 115 |
| 67, 34, 197, 23, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 23 x 67 x 34 x 197 x 23 x 5 = 14243832840
Therefore, the lowest common multiple of 804,136,788,529,690 is 14243832840.
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.
804 x 136 x 788 x 529 x 690 = 31450382910720
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.
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
136 : 1, 2, 4, 8, 17, 34, 68, 136
788 : 1, 2, 4, 197, 394, 788
529 : 1, 23, 529
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 804,136,788,529,690, is 1.
Now, the common factors can be found like this.
804:2x 2x 3x 67
136:2x 2x 2x 17
788:2x 2x 197
529:23x 23
690:2x 3x 5x 23
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 23 = 2208
Therefore, the value for common factors is 2208.
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 = 31450382910720/(1x2208)
LCM = 31450382910720/2208
LCM = 14243832840
Thus, we can understand that the LCM of 804,136,788,529,690 is 14243832840.
