The LCM of 870,845,759,650 is 185992950.
Find LCM of 870,845,759,650 with Prime Factorization
| 2 | 870, 845, 759, 650 |
| 3 | 435, 845, 759, 325 |
| 5 | 145, 845, 253, 325 |
| 13 | 29, 169, 253, 65 |
| 29, 13, 253, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 29 x 13 x 253 x 5 = 185992950
Therefore, the lowest common multiple of 870,845,759,650 is 185992950.
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.
870 x 845 x 759 x 650 = 362686252500
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.
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
845 : 1, 5, 13, 65, 169, 845
759 : 1, 3, 11, 23, 33, 69, 253, 759
650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 870,845,759,650, is 1.
Now, the common factors can be found like this.
870:2x 3x 5x 29
845:5x 13x 13
759:3x 11x 23
650:2x 5x 5x 13
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 5x 5x 13 = 1950
Therefore, the value for common factors is 1950.
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 = 362686252500/(1x1950)
LCM = 362686252500/1950
LCM = 185992950
Thus, we can understand that the LCM of 870,845,759,650 is 185992950.
