The LCM of 764,897,690,171 is 195312780.
Find LCM of 764,897,690,171 with Prime Factorization
| 2 | 764, 897, 690, 171 |
| 3 | 382, 897, 345, 171 |
| 23 | 382, 299, 115, 57 |
| 382, 13, 5, 57 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 382 x 13 x 5 x 57 = 195312780
Therefore, the lowest common multiple of 764,897,690,171 is 195312780.
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.
764 x 897 x 690 x 171 = 80859490920
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.
764 : 1, 2, 4, 191, 382, 764
897 : 1, 3, 13, 23, 39, 69, 299, 897
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
171 : 1, 3, 9, 19, 57, 171
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 764,897,690,171, is 1.
Now, the common factors can be found like this.
764:2x 2x 191
897:3x 13x 23
690:2x 3x 5x 23
171:3x 3x 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 3x 3x 23 = 414
Therefore, the value for common factors is 414.
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 = 80859490920/(1x414)
LCM = 80859490920/414
LCM = 195312780
Thus, we can understand that the LCM of 764,897,690,171 is 195312780.
