The LCM of 870,702,431,663,430 is 32070059190.
Find LCM of 870,702,431,663,430 with Prime Factorization
| 2 | 870, 702, 431, 663, 430 |
| 3 | 435, 351, 431, 663, 215 |
| 5 | 145, 117, 431, 221, 215 |
| 13 | 29, 117, 431, 221, 43 |
| 29, 9, 431, 17, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 29 x 9 x 431 x 17 x 43 = 32070059190
Therefore, the lowest common multiple of 870,702,431,663,430 is 32070059190.
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 702 x 431 x 663 x 430 = 75043938504600
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
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
431 : 1, 431
663 : 1, 3, 13, 17, 39, 51, 221, 663
430 : 1, 2, 5, 10, 43, 86, 215, 430
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 870,702,431,663,430, is 1.
Now, the common factors can be found like this.
870:2x 3x 5x 29
702:2x 3x 3x 3x 13
431:431
663:3x 13x 17
430:2x 5x 43
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 3x 3x 5x 13 = 2340
Therefore, the value for common factors is 2340.
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 = 75043938504600/(1x2340)
LCM = 75043938504600/2340
LCM = 32070059190
Thus, we can understand that the LCM of 870,702,431,663,430 is 32070059190.
